I don't think this item would really work as an actual belt, but it is great for the reason I bought it.  I sing with the band at church and our in-ear monitors are powered by heavy battery packs.  This is no problem for the guys who always have the waistband of their pants on which to hook the pack, but for the girls, it's a problem if we're wearing a dress.  This is the perfect solution.  The belt is very thin, so it really doesn't even show when worn over a dress, and it provides a place to hang the pack within reach so that volume, etc can be easily adjusted.
