There's one inexpensive brand (I thought it might have been Look-It, but from another post that seems unlikely. I do know it's not Satara.) that doesn't actually say the brand inside the leotard, just a very small tag with size and a slightly larger one with the materials listing. They've got some pretty nice stuff, but if you find this brand and end up going with it, they run rather big (at least compared to Garland and GK, ones I could dig up that *did* say the brand in the tags).
As in I'm not tiny (5'7", not flat chested, 38 or 40 depending on how tight I want it to fit in Speedo and Arena and other bathing suits that measure size that way). and an adult large is too big for me, where it's pretty snug in every other brand I've worn. Though this was years ago, so they may have adjusted. Just throwing this out as a warning to check before making a big order. But I suppose it's good if you've got unusually large gymnasts...I didn't think they regularly made them for people that big!
Metallic nylon and foil is a nice way to stand out on a beach if you're not a bikini person...my non-velvet ones have been repurposed as swimsuits in the last several years. ;-)
