To determine your bra size, you take two measurements -

1. Under bust Measurement
Measure under your bust, and then:
add 4ins. if the measurement is an even number of inches
add 5ins. if the measurement is an odd number of inches.

(For example, if your under bust measurement is 31ins., add 5ins. to obtain bra size 36 or, if your under bust measurement is 34ins. add 4ins. to obtain bra size 38)

2. Over bust Measurement
Measure round the fullest part of your bust to determine Cup size.
If the over bust measurement is the same as the figure determined above, your Cup size is A.
1in. more gives Cup size B
2in. more gives Cup size C
3in. more gives Cup size D
4in. more gives Cup size DD
5in. more gives Cup size E
and so on…..

An example:
Under bust measurement of
33in. + 5in. = bra size 38
Over bust measurement of
42in. = Cup E

So the correct fitting would be 38E

Please note that this guide is only intended to provide a general indication of your bra size.  Please also bear in mind that sizes vary between manufacturers and between different styles of bra. So what fits perfectly in one style or brand, may not in another.

Are you wearing your correct size?

Bra rides up at back? . . . adjust hook and eye closure to tighten, loosen straps or try a smaller band size (for example 36 instead of 38).

Band digs in? . . . try one band size larger (for example 36 instead of 34) or opt for a bra with a wider band.

Sides bulge? . . . order one band size larger (for example 36 rather than 34) or choose a style that provides more support and cup coverage.

Cups overflow? . . . order one cup size larger (for example C to D) or one band size larger (for example 36 to 38).

Sore shoulders? . . . loosen bra or opt for a bra with wider, or padded straps.

Bustline sags? . . . shorten straps or choose a firmer support style.

Underwires pinch or poke? . . . order one cup size larger (for example C to D) or try a wire free (soft cup) style.

Straps slip? . . . tighten straps or opt for bra with wider straps.
