Gender-Fluid Swimsuits: A Complete Guide to Modern, Inclusive Swimwear
Gender-fluid swimsuit design has rapidly evolved over the last decade. What began as small innovations for trans women and nonbinary swimmers has expanded into an entire fashion category—one that intentionally blurs gender lines, emphasizes self-expression, and allows wearers to shape their beach persona in whatever direction they desire. Today, gender-fluid swimwear includes an enormous range of silhouettes: MTF feminizing suits, camel-toe creations, tucking designs, pouch-only micro styles, gender-neutral minimal coverage, bikinis, thongs, G-strings, and ultra-micro variations.

This article breaks down all of the major design families, how they are used, and who gravitates toward each style.
1. What Makes a Swimsuit Gender-Fluid?
A swimsuit is gender-fluid when:
✔ It can be worn by any gender without modifying the design
These are silhouettes that don’t depend on traditional male/female contours—flat fronts, small pouches, or designs intended to hide or soften genital outlines.
✔ It lets the wearer present in a different gendered direction if desired
This includes MTF feminizing swimsuits, tucking suits, and designs that intentionally create a feminine camel-toe appearance.
✔ The cut is meant to focus on the style, not the anatomy
Most gender-fluid swimwear prioritizes expression, minimalism, eroticism, athleticism, or aesthetic symmetry, rather than fitting into a “male” or “female” category.
✔ It works for a wide range of identities
- Trans women (no-op and pre-op)
- Nonbinary people
- Gender-fluid individuals
- Men exploring femininity
- Femboys
- Crossdressers
- Cis men who simply like the fit
- Swimmers who prefer sleek, micro designs regardless of gender

Bikini cuts are often the “gateway” into more extreme designs such as thongs, micro bikinis, V-strings, or thong-front tucking suits.
7. Gender-Fluid Thongs & G-Strings
Thongs and G-strings are popular because the back coverage is universal—any gender can wear them—and the front can be tailored to masculine, feminine, or neutral presentation.

This is where things become truly bold.
Ultra-micro gender-fluid suits include:

These designs are not about gender—they’re about minimalism, eroticism, and self-expression.
