Key fit areas



The underband should be horizontal across your back. It should be snug but with enough room to fit two fingers underneath it



The wires at the front should sit flat at the breastbone between your breasts



Your breasts should be fully enclosed in each cup and there should be a smooth line where the cup ends



The bra straps should be secure, but not tight. If you drop the straps, the bra should stay in the same place

Top tips for checking if your bra fits


Ill-fitting cups?

Go up a back size if:

  • Your breasts are spilling out of the cups at the front or under the arms

Go down a back size if:

  • The cups are wrinkling or gaping

Underband riding too high?

Go up a back size if:

  • The breast tissue under your arms is bulging over the underband

Go down a back size if:

  • Your breasts are showing beneath the underband
  • The underband is riding up your back

Straps slipping off?

Loosen your bra straps if:

  • They are digging into your shoulders
  • They feel tight and are causing the cups to dig into your breasts

Tighten your bra straps if:

  • They are slipping off your shoulders
  • If you have narrow shoulders, avoid balcony bras as these have wide-set straps

What about the wires?

Go up a back size if:

  • The wires are digging into your breast tissue
  • The wires are lifting away from your breastbone

Go down a back size if:

  • The wires are slipping down your body, towards your waist

How to look after your bra


Looking after your bra will help maintain its fit over time

  • Wash at 40°C or less
  • Wash light and dark colours separately
  • Use a whites detergent with brightening agents to prevent greying
  • Wash your bras in a delicates bag or pillowcase
  • Avoid tumble drying padded bras to prevent the cups distorting
  • Re-shape padded bras while damp so they dry in the right shape
  • Store bras upright to avoid crushing. To help the cups keep their shape
