What is a T-Shirt Bra?
A T-shirt bra has a moulded, seamless cup that gives a smooth silhouette under thin or fitted fabric.
Who is a T-Shirt Bra Best For?
This style works best for everyday wear under fitted tops. Recommended size range: all sizes.
How to Make Sure Your T-Shirt Bra Fits
- Cup should be smooth — no wrinkles or gaps
- Underwire should encircle breast tissue completely
- Centre gore should sit flat
How to Size a T-Shirt Bra
Use your everyday bra band and cup measurement as the starting point. Use your true measured size unless the brand sizing guide says otherwise.
Best Bras of This Type
- Wacoal — premium fit, runs true to size.
- ThirdLove — half-cup sizes for in-between fits.
- Panache / Freya — full-bust D–K options.
- Aerie / Lively — comfortable, affordable everyday fits.
Common Issues with T-Shirt Bras
- Band too loose — sister-size down for tighter support.
- Cup gap at top — sister-size up or try a fuller-cup version.
- Straps slip — adjust shorter or use a racerback converter.
- Band rolls — fabric is too thin or sized too big.
