How to measure to determine your Bra Band size, if needed.

If you do not know your current or most recent bra band size, use a measuring tape to measure around your torso

directly under your bust line, where a bra band would sit. The tape should be snug and level.

Once measured, round that number to the nearest whole number. 

If the number is even, add four inches. 

If the number is odd, add five inches. 

Your band size is the sum of those 2 numbers. 

For example

If you measured 30 (even) inches + 4=34 bra band size. 

If you measure 33 (odd) inches + 5=38 bra band size. 

All garments may also be worn FLAT, without breast forms.

You may ALWAYS email us for any personal sizing assistance at
