|Measure your bust circumference loosely,
measure your chest circumference, under the bust, as tight as possible without indenting the skin.
Measure your bust and your chest circumference
Determine your cup size
For example: A woman with a 31 inch chest adds 5 inches to determine that she wears a bra with a 36 inch circumference. If her bust measures 36 inches she wears a C cup. If her bust measures one inch less – 35 inches, she wears a B cup; one inch more – 37 inches, a D cup.
The Relationship Between Home-sewing Pattern’s and Bra Sizing
The commercial pattern companies use the same system, but traditionally draft their patterns with a B cup. Their sizing charts give a bust measurement two inches larger than the chest measurement – an AA cup size, but because the pattern’s bust measurement is four inches more than the chest measurement the pattern’s true cup size is a B.
