So the reviews on sizing are mixed here, some say order up some say order down, I say order a size down. I knew I wanted a super skin tight and that’s exactly what I got! It was perfect. Not sure what everyone is talking about a smell cause mine didn’t smell at all also didn’t make me sweat either. For everyone asking about washing I flipped mine inside out washed on a cold short cycle then flipped it back right side and hung it, no damage or anything.
