Underwear should do more than just fit—it should make you feel good. Whether you're a full brief fan, a thong devotee, or somewhere in between, we’ve got you covered (literally). At The Foundation, we’ve curated a selection of women’s underwear that’s supportive, soft, stylish and, most importantly, comfortable enough to wear all day.

From breathable cotton basics to silky lace and invisible microfibre, our collection includes full briefs, bikini cuts, hipsters, G-strings and shapewear options to suit every outfit and every mood. Explore best-selling styles from Chantelle, Simone Pérèle, Janira, Triumph and more—designed to move with you and never dig in. Whatever your go-to style, we’ll help you find the perfect pair.

What styles of women’s underwear do you offer?

We offer a full range—including full briefs, bikini briefs, hipsters, G-strings and shapewear styles. Each one is designed to offer a different mix of coverage, support and comfort, depending on what you’re wearing (and what you like).

What’s the most popular everyday style?

Full briefs and bikini briefs are long-time favourites for everyday wear. Seamfree or microfibre styles are also great for no-show comfort under fitted clothes. And for those who love a barely-there feel, thongs and G-strings are a go-to.

Which underwear fabrics are best?

It depends on what you love. Cotton is breathable and natural, great for sensitive skin. Microfibre gives that smooth, invisible finish, while lace adds a little elegance. We stock them all, so you can mix and match your favourites.

Do you offer fittings for underwear?

Yes, we do! Visit us in-store at Neutral Bay, Rozelle or Bowral. Our team can help you find your perfect size and recommend underwear styles that suit your body and outfit preferences.

How do I wash and care for my underwear?

Most pieces should be washed in cold water on a gentle cycle (or hand washed) and air dried to maintain shape and softness. For lace or delicate styles, a lingerie bag helps protect your undies in the wash.
