Hello, Everybody! Hope you all had an amazing Halloween!! As most of you know, my “definitive guide” thread was just recently pinned to the top of the board! Woo! 
It received an overwhelmingly positive response and several people got in touch with me after about additions, corrections, etc. But one, in particular, stood out. Member “Boheric” contacted me about adding a whole other guide on how to identify the Halloween (1978) coveralls and how to find an accurate pair today. I loved this idea, but the definitive guide thread was too large, so we decided to make it it’s own thread and to include a link in the other thread. This post was written by Boheric and edited by myself 
DISCLAIMER: This analysis is not meant to be seen as the end-all-be-all final say on the H1 coveralls. Many of the points throughout this analysis have a subjective element, and almost all of them are limited by the coveralls that I have seen either first hand or online. If you have seen pairs of coveralls that conflict with my analysis, please mention it so that amendments can be made, and if possible share a picture for future reference.
Huge thank you to Boheric for putting ALL of this info together!! You rock!!! 
So without further adieu, I present to you… “A Guide to Indifiying Halloween (1978) Coveralls and more.”
Trying to hunt down the exact brand, color, AND specific stitching pattern of the H1 coveralls will prove to be a daunting, near impossible task for anyone who decides to undertake it. I’ve decided to do a bit of an analysis on the popular brands that are considered go-to’s for h1 coveralls; I’m going to go over the pros and cons of each, and give some suggestions on what to do with each in order to achieve better accuracy.There are several major areas that I feel are quite important when it comes to accuracy, and I’m going to judge the brands based on how many of these areas they get right on average. My analysis is necessarily limited, for I can only judge the coverall patterns that I’ve seen, and I am happy to change my information based on you all’s suggestions. The accuracy areas are:
Chest Pocket Construction:
This covers not only the front pocket flap, but also the size and shape of the pockets as well. The pockets, as well as the actual flap, were quite large. They seemed to be single stitched and were very flat, and seemed to have the sort of rounded square look to them. It is more than likely (judging from BTS pics) that the pocket flap was stitched at the side- much like the Halloween II coveralls.

Back Construction:
The H1 coveralls had a smooth back with pleats at the shoulders. This is most evident from the schoolyard scene right before the film cuts away to Michael getting into the station wagon, as well as some BTS photos of Michael standing at the closet door, and the over-the-shoulder picture of Michael grabbing the boy in the schoolyard scene.

Waist Pocket Construction:
The waist pockets are made up of 2 small, thin pockets that are within eachother. Member zac_crook previously pointed that there was no hammer loop on the H1 coveralls, but in this thread (https://forum.michael-myers.net/t/h1-1978-coverall-pockets/53855/1) member “Kaizu” posts some pictures that say otherwise, and even changed zac’s mind! In the first photo, it looks like there isn’t a hammer loop in a typical position on the left leg when Michael gets in the station wagon. This is contrasted by one of Kaizu’s screenshots of Michael right after he has broken through the kitchen door, where there appears to indeed be a hammer loop.

Position of the Lower Collar Snap:
While the top button closure gets the most attention, the bottom snap closure and its position in relation to the zipper and front pockets is also very important. From my eyes, the closure on the H1’s coveralls seems close to parallel with the top of the front pockets.

Collar size:
This is what I think trips up most modern coveralls. The 70’s coveralls all had pretty large collars, and this paired with the low positioning of the lower snap enclosure allows for the H1 look we all know and love.
As of now, I have yet to find a pair of coveralls that gets all of these things right. I’ll now begin my analysis of the major brands, starting with…
Big Macs

Big Macs are thought by many within the community to be the brand of coveralls used in H1. One reason for believing this is that one of the makers of the film mentioned that all character’s costumes were bought at JC Penney, and since big mac was the primary brand of coveralls sold by JC Penney at the time. While it is entirely possible that the H1 coveralls were indeed Big Macs, there are a few features across the pairs that raise some doubt. First: almost every pair of Big Macs (that I’ve seen) has an overlapping, rounded pocket flap with a button. As the previous picture shows, the H1 coveralls had a side stitched, squared pocket flap with no button. Second: Every pair of Big Macs, that I have seen, have at least two seams running up to the shoulders from the waistband in order to create the side vents, and most have the seam straight up the middle. As shown by the previous reference pictures, the H1 coveralls had a completely seamless back, and its side vents were made through pleats at the shoulders. Third: As mentioned by TheGhostlyShape in his analysis, a lot of the big macs seemed to have come in the herringbone pattern, whereas the H1 coveralls were solid. Finally, most pairs of Big Macs that I have seen have a double stitch pattern on the front pocket, where the H1’s were single stitched. Despite these inaccuracies, the big macs are still a great choice for capturing the general look of the h1 coveralls and they are moderately available through eBay. Big Macs are also one of two brands that regularly have the button top neck closure instead of the snap. They also have a perfect collar size and bottom snap enclosure placement. Also, it is entirely possible that there was a pattern available with a stitched, square pocket flap, single stitch front pockets, completely seamless back, and solid fabric construction, but it is just VERY odd that it would be so rare.
Possible fixes for accuracy: it’s hard to make suggestions for improving accuracy on the big macs, since most of the issues have to do with their stitching itself. For instance, one cannot really fix the seams on the back without possibly removing the entire back portion and replacing it with a solid one.
Sears

While Sears are known to be the coveralls used in Halloween II, I have not seen much mention of them being used in H1, which is surprising considering how many of the accurate features that they possess. The Sears come standard with a squared, single stitched pocket flap, but I have seen a pair or two with the overhanging flap as well (there is always an outlier 
). The pocket flap on most Sears appears to be the proper size compared to the H1’s. While the large majority of them come with the snap top neck enclosure, pairs do exist with a button enclosure. The front pockets appear to be the right size in most cases, but they tend to be a bit too rounded to be the H1’s. Also, the front pockets seem to have a “wavy nature” along the stitching, which contrasts the flat nature of the H1’s. The bottom snap enclosure has always been in the perfect spot on the pairs that I have seen. One problem that I have noticed is that the 3 seam back design also seems somewhat common with the Sears. Mine (Boheric’s) have it, and many of the pairs I’ve seen on Ebay have it. However, I have seen others without it. Kaizu’s pair, for instance, does not appear to have the seam up the middle. The majority of the pairs that exist have with a hammer loop, but my (Boheric’s) pair does not have one, and it also sports a single tool pocket on the right leg as opposed to the standard dual tool pocket. The collar size is perfect. Overall, the Sears coveralls appear to be a mixed bag. Most of the components of the H1 coveralls are there, but it’s uncertain how likely it would be for all of these components to come together into one pair.
Possible Accuracy Fixes: The Sears seem to have a bit more plasticity compared to the Big Macs. For instance, the inaccurate snap top neck closure can be easily replaced by a button closure. However, the larger inaccuracies, such as the 3 seam back or the roundness of the front pockets, seem too difficult to effectively change.
Roebucks

Roebucks are a bit odd. I’m almost certain that they weren’t used as the actual H1 coveralls, but they consistently get most of the accuracy features right. The 3 pairs that I’ve owned and every pair that I’ve seen online has the correct pocket flap design and seamless back, and many of the inaccuracies are very slight; for instance, the lower neck snap closure is slightly too high. The most glaring inaccuracies that I can see are that they, at least in every case that I’ve seen, come with the top neck snap closure, and one thing that is pretty subjective. Another thing that I’ve noticed: The size and shape of the front pockets. While we get very few clear shots or BTS pictures of the front pockets, and the few that we do have almost always obscure one of the pockets so we never see both of them clearly, the scenes and pictures that we DO have lead me to believe that the roebucks lose a bit of accuracy in this area. One issue is the size; the entire construction of the front pockets on every pair of Roebucks that I have owned is smaller compared to my pair of Sears:

While this picture isn’t the best, it might help to see the measurable difference between the pockets on each pair. Width-wise, they are both 5 inches across, but the difference is in length. The pockets on the Roebucks are 5.5 inches long, whereas the pockets on the Sears are 6.5 inches long. Also, this length difference carries over to the pocket flap, where the Roebucks’ flap is 1.5 inches long and the Sears’ is 2 inches. While the difference is only 1 inch, I feel it is pretty apparent, and the shorter length of the Roebucks slightly accentuates the roundness found in both theirs and the Sears’ overall front pocket design, which can be considered an inaccuracy when compared to the H1’s. While the H1’s seemed to have somewhat rounded edges, the overall shape of the pocket seems squared, at least to my eyes. Some of the Roebucks that I’ve seen also have the somewhat wavy look near the stitching on the front pockets, which contrasts the flat look of the H1’s have in most pictures. One of my (Boheric’s) pairs, however, does have the flatter pockets. The Roebucks also come with two seams on the pocket flap, but I do not view this as a big issue for reasons that I’ll state below. The Roebucks also get everything right with regards to collar size, a tool pocket on the right leg, and a hammer loop on the left; while the H1’s may not have appeared to have one in some scenes, it’s nice to have the option and is easily removed if you choose to do so. In terms of availability, I’d rate them between Sears/Big Macs and Montgomery Ward’s. The ones that I’ve seen are almost always solid colors and a poly-cotton material, whereas many Sears and Big Macs are either herringbone or denim. Overall, Roebucks get some things slightly wrong, but they are very accurate to the H1’s.
Modifications to Improve accuracy: One of the best things about Roebucks is that the majority of the inaccuracies can be easily modified. The top neck snap closure can be easily replaced with a jean button, the bottom closure can be removed and replaced with one slightly lower one, you can remove the top seam on the pocket flap, and the hammer loop can be easily removed if you choose to do so. While I doubt that Roebucks, at least in the common configuration that I’ve found, were used as the actual H1 coveralls, they are damn good imitators with a bit of work.
Reeds

After purchasing my (Boheric’s) pair of Reeds, I realized that one has to make a distinction between the spruce reeds found on Ebay and the reeds bought from websites such as Gulf Atlantic Supply. The main difference between these is the presence of elastic at the back sides of the waistband. The elastic is present on most eBay Reeds, whereas it isn’t on the GAS (Gulf Atlantic Supply) Reeds. Another difference is the pocket shape. The eBay Reeds have a rounded square look, whereas the GAS Reeds have a sort of octagonal look to them. Reeds do have the proper pocket flap, but the sizing is a bit off in that the flap seems a bit too narrow in comparison to the pocket. The flap also has two seam lines like the Roebucks, but as I said before this is an easy thing to modify. The pockets themselves are quite large, and remind me of the H1’s, at least in this aspect. Regarding the back, both the eBay Reeds and the GAS Reeds come with the seams up to the shoulders. Interestingly, the back pockets also have seams across them, but I’d imagine this is not hard to remove. Reeds do not come with a hammer loop, but they do have a dual tool pocket. Like the Sears and Roebucks, the Reeds also have the top neck snap closure, and the bottom snap closure is higher like the Roebucks. The biggest inaccuracies come from two aspects: The size of the collar and the solid bottom of the arm cuffs. From the seam, the Reeds’ collar is 2.5 inches, while the Roebucks and the Sears are roughly 2.9 inches. While this is a fairly small difference, it along with the high positioning of the lower neck snap closure lead to the collar’s opening to be considerably smaller than that of the other coveralls. Regarding the solid cuffs, there’s no slit up the seam in order to accommodate a snap or button closure. Overall, the Reeds have some inaccuracies, but some of these can be fixed quite easily like the Roebucks, leaving you with a solid pair of H1 coveralls. One of the biggest pluses of the Reeds coveralls is that they have a pretty high availability rate when compared to the other brands, rather than having to scour eBay hoping for a pair of accurate Big Macs, Sears, Roebucks, or Montgomery Wards in the proper color and size. One can simply buy a pair of reeds in most sizes from either GAS or Ebay, at least at the time this analysis is being written.
Modifications to improve accuracy: You can make many of the same modifications as the Roebucks coveralls, with a few that are exclusive to the Reeds. You can make your own arm cuff slit by cutting along the seam, resewing each side of the slit and adding a snap button closure. For the GAS reeds, I believe it is possible to add the elastic to each side of the waistband, but I’m unsure about how in-depth of a modification this is.
Summary
While the exact brand, color, and specific pattern of the H1 coveralls will likely remain a mystery, there are plenty of coverall options that do a great job of getting the look right, especially if one is willing to do a bit of modification.
Well, folks, that is all! Great job and hats off to Boheric for making this awesome guide and handing the reigns over to me to edit and post it!
Have a great day, guys.
good stuff dude! 
Beautiful brother, Boheric killed it along with your editing. Congrats gents on another fine piece without a doubt.
