Full measuring guide

The Temptress Trilogy Lace Thong in Onyx is a black lace thong, the bottom piece of the Temptress Trilogy set. Sold on its own so you can replace a piece, add a second, or build the set one item at a time.

The lace is 78% nylon, 22% spandex: soft, four-way stretch, quick to recover. The front is a lace panel in the Onyx colorway; the back is a thong string. It is light enough to forget under the matching skirt.

Sizes run S through 2XL. Between sizes, take the larger one for a relaxed rise or the smaller for a snug fit; the size guide lists hip measurements. Cut and sewn in Colombia in our own workshop.

Quick answers

Does it match the bra exactly?

Yes. The thong, the underwired bra, and the skirt are cut from the same Onyx lace.

Can I buy the set instead?
