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.
Firmly hold your tape measure around your waist/ under your boobs to measure. What is this in inches?
Underband measurements are in even inches - 28, 30, 32, 34 etc.
If your measurement is an odd number e.g. 31 inches, you write down the next even number i.e. 31 becomes 32.
Loosely hold your tape measure around your boobs (in line with/ over your nipples) to measure. What is this in inches?
If you're in between inches, go up. Now, how many more inches this is compared to your underband measurement (not size). e.g. 29 inch underband / 35 inch cups = +6
Follow our grid below to find your bra size.
FIND YOUR BRA SIZE
Using our rough guide above.
You might find that you need to go up a cup size from your measurements but keep the back size the same/go down a back size, especially when boobs get bigger, so instead of a 32FF >> 30G or 32G.
Our underband size runs tight but it might just be that you need a bigger cup size, as the same underband size feels tighter with a smaller cup.
NB: we have only included our size range below for ease of finding your peBe bra. If you're coming up in a bigger cup size than our range features, e.g. 32GG, then you can use your sister size of a 34G and buy a peBe sports bra.
MEASURE USING YOUR BRA
Your bra must be a) wired and b) not more than 6 months old.
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.
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.
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.
