12K Bras & Swimwear

The perfect bra starts with the perfect size. If you know your size is 12K and you are looking for the perfect fit, you'll want to make sure that:

  • Your 12K bra fits snugly around the back and sits evenly on the body from front to back.
  • Underwires must sit flush against your chest.
  • Your whole breast is fitting into the cup with NO spillage or gaping.
  • You should be able to fit your finger under the straps.

If you are unsure of your size, visit our fitting advice page to learn more about your size, or you can contact our fitters for a virtual phone or video fitting. Otherwise, check out our selection of 12K bras and swimwear below. If your purchase is $150 or more you'll get free shipping anywhere in Australia.
