The 0-20 size range is drafted for B cup, with an average height of 5'-6".

Cup size = difference between full and high bust (1"=A, 2"=B, 3"=C, 4"=D). If your difference exceeds 2", you may need a full bust adjustment.

Measurement	14	16	18	20	22	24	26	28	30	32

The 14-32 size range is drafted for D cup, with a pear-shaped lower body and an average height of 5'-6".

Cup size = difference between full and high bust (1"=A, 2"=B, 3"=C, 4"=D). If your difference exceeds 4", you may need a full bust adjustment. If your difference is smaller, you may need a small bust adjustment.
Note: even if your numeric size overlaps with the 0-20 range, body measurements are not the same — always size by measurements, not past size.

Spans the same body measurements as the 2023 chart but introduces additional sizes for finer gradation.
Used for all alpha-sized patterns released from 2024 onward.

How to Choose the Right Size Range For You

Since there is some overlap between our two size ranges, you may be wondering which one to choose. The main difference between the two size ranges is that the 14-32 range is drafted for larger busts with a more pear-shaped lower body. If you fall in one of the overlapping sizes, we suggest determining your cup size first by measuring your full bust and high bust and subtracting one from the other. Each inch difference equals one cup size. If you are a D cup or larger, our 14-32 range will ensure the best fit through the bust. If you are an A/B/C cup through the bust and less pear-shaped, the 0-20 range will be the best option.

Suggested Fabric

For a soft and draped effect, choose midweight wovens with moderate drape, such as Tencel, lyocell, and viscose suitings. For a more structured look, try midweight wovens like linen and cotton broadcloth, or lightweight denim and twill.

Beautiful colour and feel.

So fun!

Making the Florence Top from Merchant and Mills (First time making a garment for myself that’s not just a plastic toile from a bedsheet!). Fabric has so far been really easy to work with (so great for a beginner) and the pattern is cute! We grow and eat a lot of garlic so this print felt like a must.

Amelie and Learn to Sew Knits

The last time I sewed with knit fabric was over 20 years ago; total disaster. When I saw the CC class, I immediately signed up. Loved every second; clear, precise instructions. I am so proud of my long sleeved t-shirt, I just ordered enough Luxe Organic Cotton Jersey Knit for four more in different colors.
Thank you, Heather and team.

Interesting Community

I enjoy reading the histories of what people have made.

I have not yet sewn any of the pattern releases. The styles are too body-conscious and/or retro for my taste, but the instructional videos offer a lot of information I can take to other projects.

What a great 'club'!

I've been tempted since the first year of Crew to become a member and took the plunge in January this year. It's been such a great 'club' to join! Sewing can be a bit of a solitary hobby but this online community is kind, supportive, helpful and so creative. The patterns are outstanding - clear instructions, impeccably drafted and so much support from the Closet Core team. I'm always inspired, even if I don't have as much time to sew as I'd like. I wish I'd signed up earlier!

Beautiful dress; Excellent pattern!

This was my first purchase with you, and I will definitely be back for more. The ease of purchase, detail of instructions, and accuracy of the fit turned me into a huge fan. Can't wait for my next make (after I sew a second one of these dresses!)
