Bra Fitting Tips

Not all manufacturers' sizes are the same, so you might be 34B with one brand, and 32C in another.

To ensure a perfect fit for your Karen Millen lingerie, take your measurements as described below, and use the table to find out what size you are.

How to measure

The band around your ribs is your bra size (e.g. 32, 34) and the part that fits around the bust is your cup size (A, B, C etc).

First you need to find your bra size. Wrap a tape measure around your chest, just underneath your bust. The tape should be snug, not too tight, and straight across your back. Measure the under band (the part under the bust) and add 5" (13cm): eg if you measure 29" under the band 29" + 5" = 34"

Then measure for your cup size. Measure the over the fullest part of your bust, again ensuring the tape is snug but not digging into your breasts. If the measurement is in between inches on this measurement, round up to the nearest inch. Subtract your bra size from your cup measurement to find your cup size:

-1 inch difference = AA
0 difference = A
1 inch difference = B
2 inch difference = C
3 inch difference = D
4 inch difference = DD
5 inch difference = E

Example

If your bra size (the band around your ribs) is 31", add 5" = 36", and your cup measurement is 36", your bra size will be 36A.

Common problems

Your bra is too big if:

  • The bra moves up the back, or moves around. The bottom elastic band should fit firmly but comfortably around the body. Try a smaller band size (e.g. 32, 34).
  • The cups are wrinkly or baggy. This is usually because the cup is too big. Try a smaller cup size (A, B etc).
  • The straps leave marks on the shoulder. If the bra is too big around the bottom elastic band, the strap has to compensate for that, so the bottom elastic needs to be tighter round the body. If you are wearing 34, try a 32

Your bra is too small if:

  • The neckline is tight or the breasts are spilling over the top and sides. This is probably due to the fact that the cups are not big enough. Try a bigger cup size (e.g. if you are wearing a B cup try a C cup).
  • The wires are digging in the breast, at the front or under the arms. This is usually due to the fact that the cup is too small. Try a bigger cup size (e.g. if you are wearing a B cup try a C cup).
