Boylston Bra PDF Sewing Pattern
Size GuideSizing Information
Bras
I always recommend making a muslin first to test the fit of the bra. This applies not only to new patterns but also to any new fabric you decide to use.
How to make muslins (a.k.a. toiles), a fast way and a more thorough way.
If you do not have a ready-to-wear size or at a loss for what size to start with, I offer the below sizing guideline for my bra sewing patterns.
SIZING GUIDELINES
| Difference | Cup size |
| 1" | A |
| 2" | B |
| 3" | C |
| 4" | D |
| 5" | DD or E |
| 6" | DDD or F |
| 7" | G |
| 8" | H |
| 9" | I |
| 10" | J |
MEASURING
- 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. If your measurement is an even number, add 4″, and if it is an odd number, add 5″. This is the band size.
- Measure body circumference at the fullest part of the bust while wearing a bra that is supportive yet out 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 below, this difference corresponds to a B cup. If you are in between sizes, use the larger size.
Underwear
Underwear patterns are based on a waist and hip measurement.
SIZING GUIDELINES
| SIZE | WAIST (inches) | HIP (inches) |
| XS | 24 -25 | 34.5 - 35.5 |
| S | 26 - 27 | 36.5 - 37.5 |
| M | 28 -29 | 38.5 - 39.5 |
| L | 30 - 32 | 41 - 42.5 |
| XL | 34 -36 | 44.5 - 46 |

The Boylston is a versatile and supportive full frame underwire bra for everyday featuring:
- A three piece, demi cup that allows for shaping and the ability to play with prints and color combinations;
- A comfortable fabric strap that creates a flattering neckline;
- A design that is compatible for use with cut-and-sew foam, luxury linings and a variety of trim options; and
- A comfortable scoop back that lies smoothly under clothes and enhances support.
