The Ingrid bra is a larger size non-wired bra; with the added the option of a zip front closing or a hook and eye front closing.
The sizing used is the BCD (Bottom Cup Depth) method.
Determine your BCD by measuring your best fitting bra between the bust point and the wire line directly below it. All BCD sizes from 2.75 to 9.0 are included in the pattern. Combine this cup depth with 1 of 11 band sizes from 26″ (65 cm) through 46″ (115 cm), making the Ingrid Bra Pattern size range equivalent to well over 200 unique bra sizes, including the sizes in-between that are normally not available.
