First time buying a binder so I was very worried I would go too small but i think I should have gone down a size. The sizing was based off of natural chest measurements and my natural chest size was at the top end of the extra large. The xl, however, has a lot of extra fabric around the arm pit and while it does compress a little it doesn't really hold anything in place. However none of that is against the product! I did find the fabric a little itchy and it is VERY long (was almost hard to wear in pants) but a solid garment and I will likely pick up another one that is a little tighter.
