I have done a few things.
I had to cut a small hole into each one of the bands on the last set of thigh-highs so they stretched a bit more.
I removed the D-ring in the center of 24" bar for the Fetish Fantasy Series Spreader Bar n Cuff set. (The noise was driving me nuts.)
I had a harness that I purchased from a different retailer. The dildo was molded onto a base and then riveted onto the fabric of the harness. Loved the harness, hated the dildo. So I cut it off.
I've cut off scratchy pieces of scalloped lingerie
