I wasn’t sure this top would work on me, but I love it! I’m 32H and ordered a size small. Supportive enough to wear without a bra (and show off the cute open back) for a yoga, walking, or weight room workouts. I probably wouldn’t wear it running, but if you have a smaller bust it would probably work for that too! Love the higher coverage in the front. Sleeves are tight and stay in place without riding up. I like the tight sleeves but if tight sleeves will bother you, size up!
