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.


Think of everywhere your piece will touch on your body.

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.

Sexy and effective

It's super cute, the tuck is solid and pretty comfortable. My personal opinion is that the boyshorts actually offer better compression/tuck than thongs, but of course the thong is better for panty lines if that matters to you. Definitely a high-quality item and continues to prove Origami Customs' place as best in the industry for transfemme underwear.

A Wonderful New Experience

Like others I am new to tucking and very new to gaffs. I wear leggings and thongs everyday and recently started to explore another side of myself. I like the flat front look and tried to tuck using regular manthongs and it would kind of work but, I was uncomfortable and they did not hold the tuck well.

After looking into a new idea I came across this site and started researching. I sent a couple emails with questions about sizing and after receiving some very quick responses I purchased a couple tucking thongs to try. I can say I love them. They are so comfortable as the seams do not pinch my member and the back does not ride up. They stay put and so does the tuck, even while out for a walk or just watching tv.

I like these very much for work, travel and even exercising. The breathability is incredible, they keep me feeling dry and fresh and even on a long trip stay comfortable. If I run in them (not recommended by the experts but I tried anyways) they will not hold the tuck 100%, but I did not pop out entirely, so they get a pass for sure.

I will be buying more of these thongs, they are very well constructed and the quality of material is great. I have included pictures of myself in a regular manthong and with the tucking thong, I think the pics speak for themselves. I wear leggings everywhere and I am not concerned about things popping out, I have much greater confidence out and about.

Sorry for the long review. I believe a great product deserves a good review.

Incredible tuck!

This is the best tuck possible for me- and it doesn't slip down or really show with tighter, shorter bottoms. excellent choice for swimsuit or bodysuit or bootyshort coverage! Prefer these over my bikini compression gaff because of the versatility with more outfits

Took a long time, but worth the wait!

The quality was even higher than expected! The fit is wonderful and very flattering! It is by far the best gaff I own. After buying numerous products from different manufacturers, I was growing frustrated with the lack of quality available. I was worried about recycled materials not being ideal for a gaff, but they chose a fantastic fabric for the application. Origami customs did take longer than the original estimate for production, but I reached out to the team to ask for an update. They were super nice, and they explained they had people out sick for sometime. Within a day or two of emailing, my order shipped. Pricing is higher than other options, but it is reflected by the quality of materials and craftsmanship. Highly recommend


Not really working …

A normal pantie work better :/
