Questions about the Fable dress:

Q. What's the difference between the shapes?

A. The main difference is cup size. The "E" body shape has a 2.5" (6.4 cm) difference between the full bust and underbust measurements, and is suited for a B or C cup in U.S. sizing.

The "A" body shape has a 3.5" (9 cm) difference between the full bust and underbust measurements, which translates to a C or D cup.

The "S" body shape has a 5.5" (14 cm) difference and is intended for D or DD cup sizes.

Questions about the Grail:

Q. Where can I find merino wool jersey?

A. My favorite source for merino fabric is The Fabric Store.

Q. I'm new to buying knit fabric. What does "moderate stretch" and "good recovery" mean?

A. Moderate stretch fabric can easily stretch to an additional 25% of its length, and "good recovery" means that the fabric will readily return to its original length instead of permanently stretching out or sagging. Here's a handy printable stretch guide that you can bring with you when buying fabric. Make sure to print it scaled to 100%.

Q. I'm not sure which body shape to choose because my measurements (32.5-26-35" or 83-66-89 cm) are on the fence. Should I choose the E shape or the S shape?

A. Let your cup size be the tiebreaker. You'll need to take one more measurement – your underbust measurement, right over the bra band. Round this measurement up to the nearest whole, even number, and that's your band size. Compare your band size to your full bust measurement to determine an accurate cup size. If you're an A, B, or C cup (that is, 1-3" difference between your full bust and band size measurements), go for the E shape. If you're a D-DD+ cup, the S shape was made for you.


how to figure out your cup size

Example: If your underbust is 29" and your full bust measurement is 33", your bra band size is 30" and your cup size is C. Some fitting guides will tell you to add four inches to your underbust measurement, but this results in an unsupportive bra and a band that stretches out long before its time. For instance, if you've been wearing a 32B bra and find that the band is too large or stretches out quickly, your true size may actually be 30C or 30D.
