BHIS Bra Fitting Instructions
How to measure & check fit
Before the operation, take two measurements in a sitting position wearing your own bra. Measurement A exhale (stomach out) and measure under bust approximately two inches under breast crease, B measure circumference over bust.
Cup size equals: B (over bust measurement) minus A (rib/under bust measurement) resulting in your order size.
Measurement A = 38″ Measurement B = 44″
Calculate (B) 44″ minus (A) 38″ = 6″ difference (left column on measuring chart)
Bra size = 38E
To check fit:
Ensure two fingers can be comfortably placed under:
1. The band/under the front fasteners (i.e. over wound)
2. Under the armpits
3. Under the top of the shoulder strap
Check the fit daily. If it becomes too tight, seek medical advice. Do not wear a poorly fitting bra as this risks damaging the wound.
