Finding Your Band Size:
-Measurements should be taken while wearing a bra.
-The measuring tape should be held snug but not tight while measuring.
-Begin by measuring around the rib cage directly underneath the bust.
-If the measurement is even, add 4", if it is odd add 5" to result in a whole number for band size.
-For example: if you measure 30", add 4", band size will be 34.
-If you measure 31, add 5", band size will be 36.
Finding Your Cup Size:
-To find your cup size, measure gently around the body across the high point, or fullest point of the bustline while wearing a bra.
-If this measurement is one inch (1") more than your band size, your cup is an A. Two inches (2") more, cup size is a B cup. Three inches (3") more, cup size is a C, and four inches (4") more, is a D cup.
These are the general guidelines for establishing a good starting point. Sizes will vary depending on what style bra you are wearing.
