I was so excited when I ordered this leotard! I loved the way the lace looked in the picture and promptly ordered one in black. I am 14 years old, 5' 4" and 97 lbs (so pretty slender) and I normally order a P/XS in a leotard because I like my leotards to have a high leg line to make my legs look longer. I am very picky, though, about the neckline because I don't like it to plunge when I cambre back or just anytime. When I received the the leotard, unfortunately it was too small. I tried it on, and it fit sort of okay and I guess it could have worn for class, but the minute I tried to raise my arms, the neckline plunged wayyyyyy too far down. I felt super uncomfortable about it, so unfortunately I had to send it back. From the looks of it, the leotard was wide but small, and I have a long, slender torso, so that could explain why it did not fit me right.
On the positive side, there was plenty of lining on the inside and looked beautiful and very elegant, but I guess the leotard just wasn't for me. I would recommend this to my friends with shorter torsos.
I hope this helped! <3
