I have owned a few dance bras over the past couple years and this one is perfect for leotards with mesh or that are low cut. I originally purchased this bra for an Eleve leotard that is a halter neck and It works perfectly for that purpose I just wish it had a longer strap for around the neck. The bra does run very small and I am glad I went with an XL because I am not sure if an L would have worked. I am normally a 34C or maybe a 34D depending upon the brand for a T-shirt bra. Also, note that the bra is not super supportive but allows for more security in leotards with no lining and helps to smooth lines out.
