"i'm not sure where to start with this one. i ordered it in the royal color, which i love. i'm 5'6", 120lbs, 34b with a very slim rib cage and i ordered a medium as usual. it kind of hung on me? in the most unflattering way. because i always order a medium because i'd rather my clothes be a little bit looser than tighter with the small, i gave in and exchanged for the small (which i'm still waiting on). i'm not sure how the model's bra isn't showing because mine was sorts of a mess. i think this top is really cute and i'm crossing my fingers that i had just ordered mine a size too big.
overall, if you are between sizes, size down."
