A good transgender bikini should give you more than coverage. It should help you feel confident and fully yourself. At Gaff and Go, every trans bikini is made with pre-op transgender women and non-binary people in mind, using supportive construction that creates a secure, flat-front look without discomfort. Whether you're sunbathing, swimming or simply enjoying time outdoors, our designs help you show up with confidence in settings that can otherwise feel daunting.
Unlike standard swimwear, our MTF bikinis and tucking bikinis use specialised gaff panels and soft, body-safe materials that offer gentle smoothing without tape or unsafe compression. Each bikini bottom provides reliable support in and out of water, staying in place through movement, saltwater and pool dips. With a variety of colours and cuts available, you'll find options to suit your style whether you're looking for a classic black gaff bikini or something bold and bright.
If you're new to tucking in a bikini, choosing your regular size is the best starting point. Tops and bottoms are available separately so you can mix and match to suit your shape. With over 10 years of experience in gender-affirming design, Gaff and Go is a trusted choice for trans women and non-binary people looking for a bikini for transgender bodies that actually works.
Frequently Asked Questions
What is a tucking bikini? +
It is a bikini made with tucking built in, so you get a smooth, flat front without tape or a separate gaff. The bikini bottoms have an integrated panel that holds everything in place, and you pair them with a matching top for a full set. It gives you the look and freedom of a normal bikini, designed for a trans body from the start.
How do tucking bikinis work? +
The work happens in the bottoms. A gaff panel is sewn into the bikini bottoms, gently holding everything flat and secure so there is no bulge and no need for tape. You just put them on like any other bottoms and the panel does the rest. The top is then free to be whatever style you like, since it is not doing any of the tucking.
Do I need a gaff under the bikini bottoms? +
No. The tucking panel is already built into our bikini bottoms, so they tuck on their own with nothing underneath. That is the whole idea, one piece doing the job rather than layers. If you ever want extra hold for a big day out, you can add a swim-safe gaff underneath, but for most people the bottoms alone are plenty.
Which bikini bottoms give the most coverage? +
Our high-waisted styles give the most coverage, sitting higher on the hip and holding a little more securely. Standard bikini bottoms sit lower for a classic look, while the higher-cut options feel more reassuring if you want extra security or a smoother line under the waist. Both tuck the same way, so it comes down to the look and the amount of coverage you want.
Are high-waisted bikini bottoms better for tucking? +
They are not stronger at tucking, but many people find them more comfortable and more reassuring. The higher waist holds the panel snug and covers a little more, which can help you relax and forget about it. The tucking itself works the same in a standard cut, so this is really about coverage and confidence rather than the hold. Pick whichever feels right for you.
Can I mix sizes between the top and bottom? +
Yes, and lots of people do. Because we sell tops and bottoms separately, you can take one size on top and another on the bottom to match your own shape. That is one of the advantages of buying a set as separates rather than as a fixed pairing. Just check each size guide and choose what fits each part of you best.
Do the tops have room for breast pads or forms? +
Many of our bikini tops work with inserts, so you can add shape if you want it. Slot in a breast pad for a soft, natural lift, or a heavier breast form for more presence and a fuller look. That lets you set the shape you want and change it whenever you like, from a subtle finish to something bolder.
Will my tuck stay in place in the water? +
Yes. The panel in the bikini bottoms is made to hold through movement and water, so you can swim, walk and sit without a slip, even though a bikini is cut smaller than a one-piece. The fabrics keep their shape when wet and dry quickly, so nothing loosens as you go. If a visible bulge is your main worry, our swimwear bulge guide goes into more detail.
