My two dance sons have tried many brands/style of dance belts. This is the one that met their criteria. Excellent durable and comfortable elastic, cup does not bunch and looks proper in tights. Enough padding in case of accidents. The so called thong piece is longer so it does not cause major discomfort after several hours of wearing.
I'm still on the fence about the fit of this particular dance belt - it definitely sits low on the waist, but that can give some unflattering lines under tights/unitards etc. The elastic is also quite stretchy compared to others, so I'm curious to see how long it will hold up. It is quite comfortable when everything is in place, but it doesn't offer much coverage so it can take time to get things situated.
The padding in the front does a MUCH better job than the M.Stevens does of disguising what it needs to - andI feel that that is important.
