Sizing Information

Bras

There is no single measurement method to determine bra size what bra size will work for every body. The only reliable way to determine bra size is to try on finished bras made from that pattern. Given the bra sizing challenge, we recommend starting by making your ready-to-wear size.

If you do not have a ready-to-wear size or at a loss for what size to start with, we offer the below sizing guidelines for our bra sewing patterns. If you have any sizing questions, feel free to contact us!

  • When taking measurements, be sure to stand up straight and exhale fully.
  • Measure body circumference directly under the bust with the tape measure parallel to floor. Round the measurement to the nearest inch, rounding down if you are at the ½” mark.This is the band size.
  • Measure body circumference at the fullest part of the bust while wearing a bra that is supportive yet made of a relatively thin fabric. Again, keep the tape measure parallel to the floor.
  • Derive cup size by subtracting the band size from the full bust measurement. Consult the chart below to find cup size. For example, if the full bust is 36″ and the band size is 34″, the difference is 2″. Based on the cup size chart above, this difference corresponds to a B cup. If you are in between sizes, use the larger size.

SISTER SIZES

Sister sizes are bra sizes that have the same bra cup volume and underwire size. The difference between sister sizes is the size of the band. For example, the sizes 30D, 32C, 34B and 36A all have the same cup volume and use the same underwire. The difference between those sizes is the band. This blog post has instructions for how to modify the band to reach the sister sizes on this table.

I made a couple pairs with a knit jersey and the backside became bulky due to the nature of this pattern. It’s easy to make though and with power mesh, it’s fine.

Have just made my first pair of Montgomery briefs. They are just what I wanted as hate elastic that gives me an unattractive VPL. With the unique method of cutting and making these the problem elastic is eliminated. Perfect for me!
