Suggested Size Range

We look at your measurements and your cup difference to choose the best numeric size range for you. See below for our recommendation; you can also select Alpha Sizing if you'd like your size for that range specifically.

Sizes 0–20
Drafted for a 2" (5cm) cup difference, or B cup, with a more hourglass shape. It's the best fit when your measurements fall within this range — add an FBA if your cup difference is larger than 2".
Sizes 14–32
Drafted for a 4" cup difference (D cup). Best for larger frames and fuller busts — your measurements fit here.
Alpha Size Range XXS–6X
Covers the same measurements as both numeric ranges, in twelve broader sizes. Use it for alpha-sized patterns — our easy-fitting and gender-neutral designs.

Different sizes for bust, waist, hip?
It's completely normal to fall between different sizes. You'll simply blend between sizes when you're prepping your pattern — this is called "grading" and our patterns are designed for it.

We almost always suggest making a muslin (a test garment in cheap fabric) to test the fit of our patterns. This is especially important with fitted garments.
