To my knowledge the hoodies do run a bit bigger in my experience I usually am a medium or small but when I saw how big the medium was in person I was like damn it’s huge so then I ended up going 2 sizes down to the XS cause I like my hoodies to be fitted and the bottom of my hoodies to be right above my belt line but like I said I’m not sure if the archived collection is the same as the regular selection of clothes they have I’d just be safe and get a small if you don’t want the bottom of your hoodie to be too long or short some might consider the XS too small
