Simple steps to a perfect fit

Putting on your bra

  • Stand in front of a mirror and pop your bra on.
  • Lean forwards to ensure you’re filling the cup.
  • Lift the wires and lift each breast fully into the cup.


  • The bra should feel snug on its loosest hook, you shouldn’t be able to pull the band more than 2 inches away from your back.
  • Does the back ride up, do the straps dig in? You might need a smaller back.
  • Back too tight? Try a bigger back but remember the support of a bra comes from the back and not the shoulder straps.

Underband and straps

  • The under band should fit level across your body in line with the wires at the front and fit flat to your ribcage with no lifting away.
  • The wire in the centre of the bra should be flat to your chest no matter what your bra size.
  • The strap length should be adjusted to support the cup but also feel comfortable, if they fall off your shoulders you may need to tighten them or the back size might be too big, causing the bra to ride up.
  • Once you’re happy with the underband fit, you’ll be ready to move onto checking the fit on the cups…
    REMEMBER: If you’ve gone DOWN a back size, go UP a cup size and if you’ve gone UP a back size, go DOWN a cup size.


  • The wire should enclose each breast, sit right in the crease and finish under your arms, flat on the chest wall and not on breast tissue.
  • Cups should have no bulging or gaping, if you’re spilling out anywhere you might need a bigger cup.
  • Is the cup gaping or wrinkling? You might need a smaller cup.
