This would probably work for larger chest sizes. Did not work for my small B cup.

From the Lole website:
Fun and functional, the Lole Cycle dress has an inner jumpsuit with pockets for control and convenience, and mesh side panels for mobility. Stretchy, airy fabric takes you from warm-up to cooldown.
