Ruby Full Band Bra Pattern


Ruby is finally here!

The fashionable Ruby full band bra pattern can be made with or without underwires. This pattern features an off-set vertical seamed cup for the roundest styling, and a shortened upper cup for maximum lift. Our testers were amazed at the push-up look this pattern gives. The Ruby Full Band Bra Pattern has been specially designed to use with foam lining, therefore enabling you to use virtually any stretch fabric over it as a cup cover. It can even be made without foam, using low-stretch fabrics or fabrics lined with Sheer Cup Lining.

The sizing for the Ruby is a bit different from other bra patterns, in that we use the Bottom Cup Depth (BCD) to determine the size of the cup. This is the measurement from the wire line at the base of the cup up to the location of the apex. It is much more accurate than relying on Ready-to-wear bra sizing, which can differ from company to company. Determine your BCD by measuring your best fitting bra between these two points. All 13 cup sizes from 3.0 to 6.0 are included in the pattern. Combine this cup depth with 1 of 8 band sizes from 26″ (65 cm) through 40″ (100 cm), making the Ruby Full Band Bra Pattern size range equivalent to over 100 unique bra sizes.
