As a 34E, I often find it hard to wear bralette-style bras because they aren't tight enough in the band and big enough in the cups. I like my Becky bra, but it still has that issue to a slight degree. Really amazed with the Carrie, because it actually works for me. Definitely gives me uniboob, but also feel really held in and supported. I brought a medium and it works for me. The band does roll up, but it doesn't bother me. I would probably feel confident to wear this on its own as a crop top, but haven't tried yet.
