A good t-shirt bra is one of those everyday heroes that works quietly behind the scenes. It's your go-to for a smooth, seamless look under clothes—whether you're wearing a tee, blouse, or dress. At The Foundation, we offer a wide range of t-shirt bras from everyday essentials to premium pieces that blend comfort, support and invisible style.

Our collection includes customer favourites from Triumph, Chantelle, Calvin Klein, Empreinte, and more. From lightly padded styles to moulded lace cups that still disappear under clothes, there's something for every preference and outfit. Need help choosing? Pop in for a fitting at our Neutral Bay, Rozelle, or Bowral stores and let us help you find your perfect fit.

FAQs About T-Shirt Bras

1. What is the best colour for a t-shirt bra?

Nude or skin-tone bras are best under light-coloured clothing. Black works well under darker outfits. Fun fact—some shades of red actually disappear under white!

2. Can I wear a lace bra under a t-shirt?

You can, as long as the lace lies flat and your top isn’t too sheer. Styles like the Empreinte Cassiopee offer elegant lace and a smooth finish for invisibility under most fabrics.

3. How do I prevent bra lines from showing under a t-shirt?

Opt for seamless, lightly padded or moulded cups like the Triumph Gorgeous T-Shirt Bra. Make sure you’re in the right size to avoid bulging or digging in.

4. Should I size up or down in a t-shirt bra?

Not all t-shirt bras fit the same. Sizing can vary by brand and style—so it’s worth getting a professional fitting. You might wear two or three different sizes depending on cup shape and depth.

5. How often should I replace my t-shirt bra?

Every 6–12 months, depending on how often you wear it. Rotate your bras, and when your current one starts to feel stretched out or loses support, it’s time for a new one.
