I got this leotard for Christmas and it is my favorite leotard! I love open back leotards and this has a really deep open back. It's also really flattering. I'm 5'10" and the size large accommodates my long torso quite nicely. It's 3/4 sleeve but I pull it up to 1/2 sleeve so that it's (A) not as hot and (B) it pulls away a little at the chest area when I have it all the way down. I'm 5'10" and the size large accommodates my long torso quite nicely.
Other than that it's really comfortable and beautiful. So far it's held up very well and it isn't made out of the kind of lace that tears easily. I highly recommend this leotard!
