Although I generally prefer cosplaying as Michael Myers (or Jason Voorhees) I’m working on a Laurie Strode costume too. My boyfriend, who is also into horror and cosplay, thought it might be fun to do some photos and/or videos recreating scenes from Halloween 1978. And being a woman, I would probably make a more accurate looking Laurie than he would. 
I found a blue shirt that I think looks similar to the one Laurie wears during the second half of the movie (it’s at https://www.amazon.com/gp/product/B07KJX2JLV/ref=ppx_yo_dt_b_asin_title_o09_s00 in case you are interested) but I’m not sure about the pants. Of course, they are flared and high-waisted, but I can’t tell if they are actually jeans or just blue trousers. I reviewed the daytime scenes where she has on this outfit, but it’s hard to tell. Any thoughts? I know it’s not a big deal whether I’m totally accurate, but I want to at least give it a try.
I had some blue flared pants at home already, because I saved some of my 90s/00s pants in the hopes that they will eventually come back in style. But, curses, the waist was too low.
Edited to add: Just wanted to mention, I ordered a second blue shirt, just to compare which one looked better in person. I haven’t received it yet, but it’s here: https://www.amazon.com/gp/product/B014W1B7EU/
