Runs small. I am 33 inches across the fullest part of  my chest (30C/32B) and 108lbs and according to the size chart I should be in a S. I ordered a size Small. This is way too small it looks cute from afar but from angles is obvious my chest is spilling out and digs in on my 28" underbust so I'm confused why this is so tiny and a little sad because I have to return it. :( Will update this when I try out the Medium

Edit: Medium fits perfect! Looks cute :) Thanks!
