Imo this top does run small. arms were tight in the size xs and just a bit snug in the s. top is definitely versatile. i don't usually wear peplum tops due a larger chest (34d-dd) and they usually look like maternity tops on me, however this one did not. the problem with this top is the fabric in the back of the top is shearer than i'd like. you can see every bulge and bump of your bra. i felt you'd need to cover your back with either long hair, jacket, vest or cardigan. not a deal breaker becau
