Three bachelorette party accessories that were meant to be seen together: a sash, a veil, and a pair of gloves. The gloves are the part most sets leave out, and they are the part that changes the shape of the photo, which is the whole reason anyone goes looking for bride gloves in the first place.
Bought separately, these three rarely agree with each other. The veil comes from one shop, the sash from another, and the gloves from somewhere that mostly sells costumes, and the bride ends up looking assembled rather than dressed. Buying them as one bachelorette party kit skips that problem entirely.
It is a clean gift for whoever is hosting, since it is one thing to order, one thing to wrap, and one thing to hand over at the start of the weekend. Pair it with the rest of your bachelorette party supplies, or let it stand on its own as the bride's full look for the night.
