flattering one piece!
I have larger boobs and this holds me in and pushes me up. it was great suit to wear on a family vacation. revealing, but still modest. the only issues I had is that the clasp in the back would come unclipped which was kind of annoying. Wish the clasp was more secure than just a slide through clasp. other than that, would love to get a similar version of this suit!
