Full-bust swimwear, by fit
Swimsuits never run true to size, and a D+ cup makes it worse. SwimFinder uses the same cross-brand fit engine behind BraFinder to translate the bra size you already know across the swim brands that actually make your cup.

Why full-bust swim is its own problem
Most swimwear stops at S–XL, which ignores the cup entirely — so a D+ cup spills, gapes, or gets no support. The brands that solve this size their underwire tops by band and cup, just like a bra. The catch: a 34DD is not a 34DD everywhere, so finding your size still means translating across brands. That cross-brand translation is exactly what our engine does.
The full-bust swim brands we translate
- Bravissimo SwimUK band + cup
- Curvy Kate SwimUK band + cup
- Elomi SwimUK band + cup
- Fantasie SwimUK band + cup
- Freya SwimUK band + cup
- Panache SwimUK band + cup
- Pour MoiUK band + cup
- Sculptresse by PanacheUK band + cup
These all make D+ cup underwire swimwear (several to HH/J/L). v1 sizing is rules-derived and improves as we collect fit outcomes — the same way BraFinder learns.
