Get the right fit

A great fit makes a huge difference to the way your bra looks and feels. Once you’ve found your ideal bra size and style, follow our top tips for the perfect fit:

Underband

• For the perfect fit:

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

• Go up a back size if:

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

• Go down a back size if:

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

Wires

• For the perfect fit:

  The wires at the front of the bra should sit flat against your breast bone and enclose the entire breast on each side.

• Go up a cup size if:

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

• Go down a cup size if:

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

Cups

• For the perfect fit:

  Your breasts should be fully enclosed in the bra cups.

• Go up a cup size if:

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

• Go down a cup size if:

  • The cups are wrinkling or gaping

Straps

• For the perfect fit:

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

• Loosen your bra straps if:

  • They are digging into your shoulders. If you drop the straps and the underband moves, you could need a smaller back size.

• Tighten your bra straps if:

  • They are slipping off your shoulders. If you have narrow shoulders, steer away from balcony bras as these have wide set straps.
