I really, really, really hope some people are really using them for that.
@sinnedk geos are going to look huge most of the time but i find they work well with the detroit cut jeans in my opinion. otherwise, I usually just wear them with over the knee socks from AA or heat tech tights and shorts. i too love wearing my prisoner pants but make sure you size down 1-2 as they fit huuuuuge. if you have instagram, you should look at @oliverdoor or @meninrickowens for some inspo.
@accordion the sweatshirt looks good but if you do decide to size up for a slightly oversized fit, i don't think it'd look bad either.
