WHAT BRA SIZE AM I?

Ask yourself this question every six months.

Boobs are wonderful 3D things and every pair is a unique shape. For this reason, we only use tape measures as a starting point to get you into the right bra size.

If you'd prefer, you can size fit using your existing wired day bra (we've included this below the tape measure approach).

SIZE USING A TAPE MEASURE

Follow our easy 3-step guide as a start. Then use our 'fit check steps' email when your sports bra arrives to check it fits.

FIND YOUR BRA SIZE

MEASURE USING YOUR BRA

Your bra must be a) wired and b) not more than 6 months old.

UNDERBAND:

If you notice your underband riding up your back, and can pull it away from your body by 2 inches, go down one back size.

If you can pull it away by 3+ inches go down 2 back sizes.

Warning: if you've measured your back size smaller, you'll need to go up by the corresponding number of cup sizes. e.g. if you are wearing a 34D but you can pull it away by 2 inches, you'll become a 32DD.

CUPS:

If the wires are digging into the side of your boob or not sitting flat against your rib cage, you need to go up a cup size.

This should be added on to any cup size increases if you've made in the underband step.

SISTER SIZING

There are two simple principles to 'sister sizing':

1. If you go up a back size, go down a cup size. e.g. a 30DD becomes a 32D.

2. If you go down a back size, go up a cup size. e.g. a 36DD becomes a 34E.

If you go up a back size but stay the same cup size, you'll notice extra room in the cup. If you go down a back size but stay the same cup size, the opposite will happen, and you'll notice the cup is tighter.

checking the fit

Once you're in your Impact sports bra, make sure you've adjusted yourself to check its a good fit.

Scoop your boobs into the cups from the edges, adjust the underband if needed and have the straps done up tight enough! See what 'good' looks like below.

cups

✔️ Boobs comfortably inside 👆

✔️ WRAPA® tech sits flat 👆

✖️ Boobs spilling out the side / showing lots of cleavage (means cup size is too small)

✖️ Gaping fabric (means cup size is too big)

underband

✔️ Fits firmly on the loosest hook 👆

✔️ Level all the way around 👆

✖️ Riding up your back

straps

✔️ As a measure, the hook should be level with or above your armpit. 👆

✔️ Fits firmly 👆

✖️ Digging in (then loosen)️ / too loose (then tighten)
