Measuring Tips

You will need a soft measuring tape. While wearing one of your most comfortable, non-padded bras, do the following:


How to measure under the breast band size for determining your correct maternity bra size. Step 1 – Measure your band size. Get your under bust measurement around your rib cage right under your breast tissue. Make sure the tape measure is, snug around the body, straight and parallel to the floor. If you get an odd number, round up to the next even number to get your band size.
Measuring your Maternity Cup Size Step 2 - Measure your cup size. With your bra still on, measure with the tape around the body at the fullest part of your breasts. Make sure to keep the tape straight as possible. Meet the ends of the measuring tape together.


Step 3 - Calculate your cup size. To do this, you'll subtract your band measurement (from step 1)  from the cup measurement you just took (step 2). The difference between the two numbers determines your cup size. (For example, if you measure a 34 inch band size, and a 36 inch cup size, the difference is 2: which would indicate a B cup)
  • 2 inches = B
  • 3 inches = C
  • 4 inches = D
  • 5 inches = D/E (DD) (E in European sizing)
  • 6 inches = F (DDD) (F in European sizing/E in UK sizing)
step 4 - Belabumbum size range is typically as follows:

S = 32 D/E (DD), 34-36 B/C
M = 34-36 D/E (DD), 38 B/C
L = 34-36 F (DDD), 38D/E (DD)
XL = 36-38F (DDD), 40D/E (DD)

Please refer to the sizing range for each bra.
