These straps are amazing - very strong and supportive. These are by far the best belts I've ever bought. In terms of shape, the set (purchased as a set of 2) goes with multiple outfits, and in terms of functionality, these straps are life-savers and maintain a secure grip under varying pressures, so no matter your size, these things should hold up! I'm a happy customer. In my opinion, this is one of the best fashion innovations I've come across. So who invented these things. Thanks.
