I was right on the transition from small to medium on the size chart and the small fits me perfectly. The medium was loose and gapping. As someone who is small and high-chested, I still have to pull the bra down (band is about an inch below my actual breasts), but that's pretty normal for me. Slightly shorter shoulder straps would be a perfect fit, but it is a good fit as is.
Love the design! It makes me happy to put it on!
