Shirt Making for Curves

Step-by-step lessons to help you sew the perfectly fitting shirt of your dreams!

  • Do you dream of wearing a shirt that fits all your curves?
  • Do you get frustrated trying to adjust shirt patterns so they won't gape or tent at the bust?
  • Do you want to try your hand at sewing your first shirt, or want to improve your techniques, but would love a friendly teacher to give you a helping hand?

Then this is the course for you! Join me in sewing your beautifully fitted button-down shirt, tailored for curves.


Welcome to Shirt Making for Curves! In this course, you’ll learn the fundamentals of shirt making in order to end up with a professional looking, well-fitting shirt. Button-down shirts are a classic wardrobe staple but are notoriously tricky to fit at the bust. That's why the Cashmerette Harrison Shirt has been designed with curves in mind, with cup sizes from C to H - and this course will take you step-by-step through the shirt-making process so you will have a beautifully sewn shirt that fits!

Included with the course is a free* copy of the Cashmerette Patterns Harrison Shirt pattern (choose from a downloadable PDF or a paper version that will be mailed to you). Already got the Harrison? No problem! You can use your coupon for any other Cashmerette pattern.

The Harrison Shirt is designed with double princess seams for a uniquely curve-friendly fit, which won't gape or be tent-like over your bust. It features all the elements of a classic shirt, including a two-piece collar, yoke, and placket, separate button bands, and buttoned cuffs. This pattern looks equally pretty in crisp Oxford cottons at the office or cozy flannels for playing in the snow.

I hope you'll join me in this shirt making adventure!

*Shipping charge applies for paper pattern.

Hi, I'm Jenny! I founded Cashmerette because I was so frustrated with never being able to find clothes that fit my plus size, curvy body (hello, H cups!).

I learned to sew at the tender age of 30, excited by the potential of being able to make clothes that fit me, and also reflected my bold, print-loving style. But I immediately faced the same issue that I did with store-bought clothes: most of them didn’t come anywhere near to fitting me well, not least because most were designed for a B cup.

So I learned how to alter patterns and had the (literally!) life changing revelation: that I could change my clothes to fit my body, rather than changing my body to fit clothes.

And well, the rest is history! At Cashmerette we have the patterns, books, and workshops that I wish had existed when I learned to sew. This, here, is my life’s mission, and I’m so glad you’re along for the ride!

As for the rest of my life? Well, I live with my daughter just outside of Boston, Massachusetts, but I’m originally from the UK (still have the accent!), and am very familiar with the British Airways Boston-London flight schedules. When I get the time, I also love drawing, painting, and cooking fancy things.
