COVERALLS!!!

I don’t think that was the question.

Our young fellow here ask about the color, not the coveralls he should buy.

And as it was said by WhipItGouda and RanshiieKrueger84, there’s no need to speculate anymore, just a glance at the Definite Guide (The Definitive Guide to All Halloween 1-11 Masks, Boots, Coveralls, and Knives **PIC HEAVY**) is enough to learn the solution.
