Step #1
HOW TO MEASURE YOUR BAND SIZE
Every great fit starts with accurate measurements. Here’s how to find your best fit with our bras:
- What you wear matters! Start with a non-padded or lightly padded bra, or go full birthday suit if you’re alone. The best fit is found when you don’t add a lot of extra bulk or compression to your measurements.
- Measure Your Underbust: Wrap a measuring tape snug, but not tight, around your ribcage, right under your bust. Ensure the tape is straight and level around your body. This measurement, in inches, is your band size. If you get an odd number, round up to the next even number for the best fit.
- Band Size Variation for Comfort: Take a deep inhale before you measure to expand your ribcage to the largest it might be, and you’ll get a more comfy-fitting band size.
Step #2
HOW TO MEASURE YOUR CUP SIZE
- Measure Your Full Bust: Now, measure around the fullest part of your bust, keeping the tape level but not too tight. This measurement gives you your bust size, crucial for determining your cup .
- Determine Your Cup Size: Take your full bust measurement and subtract your underbust measurement. This tells you the cup size. Each inch of difference represents one full cup size. For example, a 1" difference = A cup, a 2" difference = B cup, and a 3" difference = C cup, etc.
At iteration, we use alpha-sized bras with a fuller bust option, as our garments have been created to be very fit-flexible. To find your size in our bras, you'll need to take both measurements you've found, consult the size chart below, and find where your two measurements intersect.
