I'm looking for something with a low neckline, but a high enough back to hide the (super heavy duty) sports bra, and preferably sleeves (for the hiding of the sports bra, and also my upper arms). Did not think this was a huge ask, but it seems to be. Everything long-sleeved seems to be backless. I'm a 30H. Any suggestions? Where would you shop for such a beastie? Is there such a thing as a leotard with a proper built in bra?
