Bra Size Calculator
Our patterns use actual breast measurements - instead of the usual chest circumference - for more accuracy and few muslins! For this reason, please use your measurements instead of your store bought or retail size. This calculator was created especially for LilypaDesigns Sewing Patterns - it may or may not reflect your bra size for other designers.
How to Measure Illustrated Guide
In some cases, your measurement may span 2 different size sets. In this case, select based on breast SHAPE. If you have more inner fullness and/or projection, err on the side of the larger size set. It is much easier and intuitive to adjust the band (including the wireline) vs adjusting the shape of a 3D cup pattern.
Each of our patterns are offered in multiple size sets (with a few exceptions) as each group represents a different breast shape. There are at least a 2 size overlap for convenience but they are NOT identical. Cup pattern pieces cannot be interchanged with the equivalent pattern piece in another size set without alteration.
The A-DD range was drafted for standard/wider breast roots + average projection + average center gore (3/4” or 20mm) following industry standards.
The DD-GG range was drafted for narrow breast roots + more projection + narrower center gore (3/8” or 10mm).
The GG-KK range was drafted for significant inner fullness with very rounded breast shape + even more projection + narrower center gore (3/8” or 10mm).
If you’ve tried our underwired bra patterns, you’ll find a smooth transition in terms of consistent sizing and fit. [Primer on Breast Shape HERE]
Bra Pattern Size Chart
Compare your measurements to the chart below. If your measurements span multiple sizes, this is normal and a better reflection of our individual needs as 2 people can have the same measurements but very different body shapes. Customize your fit by grading between the sizes - this includes adjusting the Bottom Cup Depth.
