Runs small, I would suggest sizing up!
Usually in the burnout style it's a more mesh stretchy-type fabric, but this isn't what it feels like, it's pretty tight even though I already ordered my size up size to a large (I'm in between sizes in between a medium and a large but will usually size up to the large because I prefer clothes a bit looser), but this is still too tight, and wish there was an XL to size up to but it's already sold out :(
