I think they just launched their gymnastics line, I saw an ad for it in Inside Gymnastics, so I imagine not much feedback on the line is out there at this point. Perhaps someone here has used them for dance though.
I used them for a piece of my Halloween costume this year! It got here faster than it was supposed to, sizing was accurate (though that is the problem of the company, as I understand it), they sent what I actually ordered...
I have ordered many leos from here and they are all well made. Sizes are funny so make sure to check. I know a couple others who have also have ordered and have been pleased.
