The Classic one-piece swimsuit  – The Ultimate Swimsuit Project

Inclusive. Supportive. Timeless. Made in Cape Town.

Meet the swimsuit created for women who love the water but refuse to settle for anything less than comfort, confidence and intelligent design. The Classic one-piece swimsuit from The Ultimate Swimsuit Project, a sister brand of Hubba Hubba, is a beautifully engineered, vintage-inspired one-piece made to support real bodies — especially plus-size and full-bust swimmers — without ever compromising on style.

Designed and made in Cape Town from high-quality Lycra, this swimsuit is durable, supportive, and built to last season after season. Whether you’re a modest swimmer, a retro lover, a frequent lane-goer, or a fellow photosensitive vampire looking for something chic yet functional, this classic black costume is your new summer essential.

Why you’ll love the classic one-piece:

• Supportive seamed, underwired cups
  Designed for clothing-style sizes paired with cup sizes (10B–26G), giving you a secure, comfortable, custom-feeling fit, in a wide range of sizes.

• Wide, adjustable straps
  Enjoy comfort and versatility. Wear them straight or cross them in a racer-back style for extra hold — perfect for active swimming.

• Powermesh smoothing in the front and back
  Unlike most swimsuits, the control actually works. Expect gentle shaping, tummy smoothing and a secure, supported feel.

• Secure, vintage-style leg line
  Creates a smooth silhouette across the hip and bum, stays put in waves, and offers flattering, modest coverage.

• High-quality Lycra for longevity
  With proper care, your swimsuit will last for years — reducing textile waste and giving you exceptional value.

Designed for Real South African Women

The Classic one-piece Swimsuit is ideal if you:

Fit Guide: Clothing Size + Cup Size

Our foundation swimsuit is constructed in clothing sizes paired with cup sizes, giving a far more accurate fit than generic S–XXL options. If you’ve ever struggled to find swimwear that supports your bust and fits your body comfortably — this is for you.

Sustainability Matters

Every swimsuit is proudly made in Cape Town from durable materials designed to last. Treat her kindly and she’ll stay beautiful for years, meaning fewer garments in landfills and more feel-good days in the sun (or shade!).
