So I ordered a small BC they were out of mediums. It fits as a small should and I can still make it work. This is super cute and will go well with just about any of my vacation skirts/shorts.. It's a smidgen tight around the elastic areas but I imagine it'd be less uncomfortable had I gotten the correct size. The sleeves ride up  any time I lift my arms but if I'm not planning a super active day it should be fine.
