Retro Summer

Our retro swimwear is where it all started. From tie-up fronts to classic bikini cuts and flattering one-pieces, this collection of summer swimwear is made to be loved and worn by small boobs.

Though the colours and cuts of every design may be different, each set is crafted to provide a natural lift that’s comfortable and smooth. And we mean it. No awkward cup gaps, no pinching at the legs or underarms, and definitely no inserts that shuffle around as you move.

LOU Swim’s retro swimwear line pairs seamless padding with sustainable summer swimwear materials that feel good and look good.

Retro swimwear made with sustainable materials

You wouldn’t know it just from looking at our designs, but our retro swimwear is made from recycled plastic bottles — seriously! We use the highest quality American REPREVE® fibres, which feel like a second skin and help us to maintain a positive impact on the environment.

Sustainability is very important at LOU Swim. When it comes to crafting our summer swimwear, our choice of material is just the beginning of our environmentally conscious production. Our swimwear is also UV protected and resilient to chlorine, sunscreen and oils, so you can enjoy wearing your bikini for many summers to come.

Our high-quality retro swimwear is crafted in limited numbers to actively reduce the amount of fabric waste from items not sold. Although this sometimes means restocks can’t happen, you can shop confidently, knowing our designs are made with the planet in mind.

Whether you’re after a bikini with a push-up effect or a one-piece that flatters small boobs, our retro swimwear ticks a lot of boxes. Start by checking out our size guide for the ideal fit and then browse our designs featuring:

  • TORI (Blue) set — The adjustable tie-up front of the TORI set is one of our most popular designs. Lightly padded for a seamless and smooth push-up effect, it’s paired with high-waisted, medium-coverage bottoms for confident wear.
  • FIO (White) set — Finally, a classic cut bikini that supports small boobs without any awkward gaps. The FIO features a clasp back and bra-like design, with a thick band that runs under the lightly padded top. It’s paired with high-cut leg bottoms that hug the body just above the hips.
