Almost nothing
A crotchless thong is a thong with an open gusset, the most minimal bottom in erotic lingerie. We make two, the Fil Crotchless Thong in lace for $32 and the Perle Pearl String for $44, both in sizes XS to 4X and both finished with soft edges.

The guide
Less, done well
A crotchless brief still frames the hips with fabric. A crotchless thong removes almost everything, leaving a waistband, a narrow line and a deliberate absence. It is the piece you choose when the body itself is the outfit and the lingerie is only punctuation. Under a fitted skirt it leaves no line at all, which makes it the most discreet of the daring options.
Because there is so little of it, construction matters more than with any other cut. The waistband has to hold without rolling, and every edge that touches skin has to be soft.

The Fil Crotchless Thong is the one for a long night out. The Perle Pearl String is a piece of theatre: the pearls warm to body temperature within minutes and shift with every step.
Take your hip measurement at the widest point and your low waist measurement where the band will sit, then pick your letter size from the size guide. A thong band should rest flat without leaving a mark. If you are between sizes, choose the larger one: a tight band on a thong pulls the back line too high and is the first thing that makes it uncomfortable.
Both thongs sit naturally under a garter belt, so the clips and straps stay on top and nothing has to come off. Add our fishnet stockings for a graphic line, or keep the legs bare and put the attention on the bust with one of our open cup bras. If you prefer more fabric at the back with the same opening, the fuller crotchless panties are the softer sister of this cut.
The thong is the right choice in three situations. The first is a fitted dress, where any line at the hip would spoil the silhouette and a fuller brief would show. The second is a garter look, because a thong worn over the suspender straps can be removed while the stockings stay in place. The third is the evening where you want the back view to be the moment, since a thong leaves the curve of the hips entirely bare.
It is the wrong choice if you want coverage at the back or if you plan to wear it for an entire working day. For those, a full crotchless brief is kinder. A thong also asks for confidence more than any other bottom; if you feel exposed, start at home with the lace version and keep the pearl string for a night when you want to feel watched.
Both of our crotchless thongs come in black, the shade that disappears under evening clothes, and each has a second color for the night it is meant to be seen: rouge for the Fil, ivoire for the Perle.
Hand wash the Fil in cool water and dry it flat. The Perle should be wiped with a damp cloth and dried at once, never soaked, so the strand keeps its shine. Thongs are final sale for hygiene reasons, without exception; if a piece arrives damaged or is not what you ordered, we replace it.
