So, if your measurement is 28 inches, add 4, making you a size 32. If
you measure 31, add 5, making you a 36.
Overbust Measurement
Measure round the fullest part of your bust to find your Cup Size.
If this measurement is:
The same as your underbust size - then your cup size is A
1 inch more than your underbust size - then your cup size is B
2 inches more than your underbust size - then your cup size is C
3 inches more than your underbust size - then your cup size is D
4 inches more than your underbust size - then your cup size is DD
5 inches more than your underbust size - then your cup size is E
6 inches more than your underbust size - then your cup size is F
7 inches more than your underbust size - then your cup size is FF
8 inches more than your underbust size - then your cup size is G
Let’s use me as an example.
- The circumference under my bust is 26 inches.
- So I add 4, giving me an underbust measurement of 30 inches.
- My overbust measurement is 31 inches, which is 1 inch more than my
underbust measurement.
- This means I am a cup size B.
- Ergo, my bra size is 30B (almost impossible to find in shops, but that’s
another story).
Problem solving:
Bra rides up at the back
– move the hook-and-eye closure to a tighter setting
- loosen the straps
- try a smaller band size (e.g. 34” instead of 36”)
The band digs in
- go one band size larger
- choose a bra with a vertically wider band
The sides bulge
– move up one band size
- opt for a style with more cup coverage
The cups overflow
- go one cup size larger (e.g. C to D).
The straps slip
- tighten straps
- opt for bra with wider straps
- choose fully adjustable straps (instead of ones which can only be
adjusted up to the top of the shoulder)
Bra leaves red marks on your shoulders
- loosen bra straps
- opt for one with wider or padded straps
Underwires pinch or hurt
- go one cup size larger (e.g.B to C)
- try a non-underwire soft cup style
There are many different styles available and moulded cups can give as
much support as underwire!
