At The Foundation, our collection of swimwear separates is all about giving you the freedom to mix and match. Whether you're looking for a bikini top, tankini, singlet or a perfectly fitting swim brief, we’ve got you covered. Our curated range focuses on flattering cuts, supportive designs, and stylish details so you can build the perfect set for your unique shape.

We proudly stock top swimwear brands like Baku, Sunseeker, Sea Level, Jantzen, and more—each offering a wide range of cup sizes and silhouettes. Whether you're heading to the beach or relaxing by the pool, our swimwear separates let you choose exactly what works best for your body and your style.

Why Choose Swimwear Separates?

Swimwear separates let you customise your fit—choose different sizes for tops and bottoms, mix colours or prints, and swap styles depending on your mood or activity. It's the most flexible and body-positive way to shop for swimwear.

Do You Stock Cup-Fit Bikini Tops?

Yes! Many of our bikini and tankini tops come in cup-fit sizing to give you the lift and support you need. We carry options from A through to G cups in selected styles and brands.

Which Bottom Styles Are Available?

We stock everything from high-waist briefs for more coverage, to classic bikini briefs, and boyleg cuts. Some even feature tummy control panels or reversible prints—style meets practicality.

Can I Try Swimwear In-Store?

Absolutely. Visit us at The Foundation Neutral Bay or Rozelle, or at Lin & Barrett in Bowral for professional fittings and expert advice on swimwear styles that suit you best.

How Should I Care for My Swimwear?

To prolong the life of your swimmers, rinse immediately after use in cool water and lay flat to dry out of direct sunlight. Avoid machine washing or tumble drying to keep elasticity and colour intact.
