Thong Gaff
Need a compression gaff that disappears under everything? Our bestselling black Thong Gaff is designed to create a smooth, secure silhouette without visible panty lines, making it one of our most-loved pieces of tucking underwear for everyday wear.
Whether you're wearing leggings, dresses, workout clothes, or your favourite pair of jeans, this gender-affirming thong stays discreet while providing our highest level of comfortable compression. Wear it with or without a tuck, depending on what feels right for you.
Unlike most trans underwear, this made-to-order Origami Customs Thong Gaff includes FREE custom sizing. We're the only brand offering custom-fit gaffs at no extra cost, creating a garment that's more comfortable, more secure, and made to fit your body, not the other way around.
High Compression Without Sacrificing Comfort or Safety
The front panel is made with two layers of our signature Powermesh, giving you our highest level of compression while still allowing the flexibility and breathability you need for everyday life.
The back features a single layer of semi-sheer mesh, creating a lightweight, barely-there feel that's just as comfortable as it is flattering.

HOW TO MEASURE
Chest/Bust: Measure around the fullest part of the chest, with arms relaxed down at sides and without a bra. Keep the measuring tape parallel to the floor. Keep the tape comfortably snug but not tight, which will include measuring the space between the chest tissue. Do not squeeze the chest tissue flat.
Ribs/Underbust: Around your ribcage where a bra band sits. Measure on the exhale. Make sure to measure under the breast tissue
Waist: Measure around natural waistline, which appears as a crease when bending to one side.
High Hip: Measure just over the hip bones, where the waistband of a low rise bottom would sit
Low Hip: Lift one leg to see the bend where the hip and leg meet. The low hip measurement is taken by measuring around the bum at this level. Keep the measuring tape parallel to the floor.
WHAT TO MEASURE
Think of everywhere your piece will touch on your body.
Bodysuits: Chest, ribs, waist, high hip, low hip, girth (optional, see below)
Bras, Harnesses: Chest, ribs. Do not send your bra size
Low Rise Bottoms: High hip, low hip
High Rise Bottoms and Swim: High hip, low hip, waist, rise (optional, see below)
Binders: Chest, ribs, waist (measure unclothed)

Thong, Cheeky, Hipster Gaffs: High hip

We’ve come up with a system where you can now select the gusset width on every bottom. Which basically helps let us know how much room we build into any garment.
You can now select from:
Narrow: "Standard" fit undies, usually found in a "women's" section.
Wide: The way we make all of our mesh gaffs already. Room for a penis, tuck or not. Also great if you have a vulva and want a bit of extra room.
Roomy: A bit more than the wide fit. For folks with a bit more down there, or a comfier fit without a tuck.
