I would say this leo runs slightly large. I ordered my small 11-year old (who normally wears size 8) a medium as per the size chart. It's labeled "8-10". We got it six months ago, and it was ridiculously loose on her. The butt hung down off of her. Now that she's grown, it's better but still big. If you're in between sizes or on the fence about which to order, order down.
She shares it with my 9-year old who is the same size and picky about comfort. There's a bralette in the front, which neither of them need yet, and she finds it uncomfortable. It doesn't always stay down.
Overall though, it looks great. It's the shiny type, so it stays nice and black, no fading. It's well made.
I have used this leotard in my ballet company for about three years now, and all the girls love them! They are super stylish and comfortable, plus they fit great on almost all of the girls. Awesome leotard, would definitely recommend giving it a try.
ordered this according to sizing chart but it was really tight on my 10 year old who is tiny. I have to return and get a larger size. I just sent it back so I am a little nervous as to how long it will take to get the replacement - paperwork mentioned 2-3 weeks. I will see. Once we get the larger size I will review the quality.
For some reason there is no size chart for this leo, but I purchased the large for my 12 year old daughter because the picture made it look like the girth (which is always our problem area with leos) looked fine. It fit her fine everywhere except...the girth. This is a problem with almost every leo - even with her older sister. They both complain that almost every leo they have - when they "cambre" - the front rides down way low on their chest and makes them very self-conscious while they're dancing. This is because very few leos are made well - to where they don't ride up in the back or the front crotch area, but have a high enough neckline that it isn't pulling down to make up for the girth length lost through the torso. We are still searching...halters are usually the best bet but some teachers demand a cami-style leo.
