We found Look-it when looking for DD, someone suggested those to us after she got too big to fit into any of the leotards you could just go buy at Kohl's.

We never really liked GK Elite because those leotards tended to run small & never quite fit right for DD. We mostly used them for the underwear items since my DD always liked to have the panties underneath. We did get grips from them too & the stuff for her hands to help with rips.
We never had a problem with any of the leotards we got from the above company.
DD was a gymnast from age 4 1/2 until 14 when she had to quit last year.
