If you’ve ever spent hours making a garment, only to put it on and find it doesn’t fit, you’re not alone. Fitting can be one of the hardest parts of sewing, but it’s also the key that unlocks everything: clothes that fit beautifully, sewing that’s actually fun, and the confidence of wearing a truly custom-fit outfit that looks fantastic.

That’s why I’m so excited to introduce Fitting University, the ultimate online fitting course from Cashmerette.

Fitting University is a comprehensive on-demand video course that teaches you how to fit sewing patterns to your unique body, with confidence. It’s the most thorough fitting resource we’ve ever offered at Cashmerette: over 90 easy-to-understand video tutorials which will help you fit any sewing pattern on your to-do list. Previously only available to Cashmerette Club members, everyone can now learn from our very best educational content!

Whether you’re brand new to fitting or you’ve been struggling with it for years, Fitting University is built to give you clear answers, exactly when you need them.

What makes Fitting University different?

Expert fitting help, from the comfort of home.

Learn from clear, in-depth classes you can access whenever you need, for a fraction of the cost of an in-person class, and without ever leaving home.

A complete fitting library, organized by topic.

The course covers the foundations of fit and moves on to tutorials by body area from full bust adjustments by garment type to rounded backs and full bicep adjustments. Then, move on to advanced techniques like fitting for asymmetry, and adding or removing sleeves. That’s over 50 hours of in-depth videos that unlock the secret to fantastic fit.

Learn the why, not just the how.

The in-depth videos go way beyond the content you can find in books or short tutorials, covering the theory behind why a garment isn’t fitting, rather than just teaching you to blindly follow steps. Master the principles to help you confidently identify issues and know how to tackle them.

Body-positive tuition you can trust.

Fitting University is taught by me, Jenny Rushmore, best-selling author of “Ahead of the Curve” and founder of Cashmerette. My teaching is deeply rooted in body positivity, and my encouraging and (dare I say?) entertaining style has helped tens of thousands of sewists around the world learn the life-changing power of adjusting your garments to fit.

Your Fitting University questions, answered

How is this different from other fitting courses and books out there?

First, it’s comprehensive — 90+ video lessons covering every body area and dozens of specific adjustments. Second, you’ll learn the why, not just the how. Most fitting courses give you steps to follow; Fitting University teaches you the principles behind each adjustment, so you can confidently diagnose and fix issues on any pattern. And third, every lesson is rooted in body-positive teaching, by a true expert in size inclusive patterns – this is the pinnacle of curvy fitting education! Previously only available to Cashmerette Club members, everyone can now learn from our very best educational content!

What level of sewing experience is it suitable for?

Any! Fitting University is designed for sewists from absolute beginners who’ve never tackled fitting before, all the way through to more advanced sewists who want to refine their skills. The course starts with the foundations of fit — what good fit actually looks like, how to take your measurements, how to choose your size — and builds from there, through to advanced lessons.

What if I don’t even know what my fitting issues are?

This is one of my favorite questions because it’s such a common issue – you can’t fix a problem if you don’t know what it is! Fitting University starts by teaching you how to evaluate fit and diagnose what’s going wrong with the pattern. Once you can spot what’s happening (and understand why), you’ll know exactly which lessons to head to next. You don’t need to arrive with a checklist; we’ll help you build one.

When can I sign up?

Right now! Fitting University is on demand, so you can sign up any time and get instant access to all the content. There’s no limited enrollment period, no waiting list — you can dive in the moment you join.

Is this a subscription?

No, Fitting University is available as a one-time purchase of $329 with lifetime access.
You can also get it for more than 50% off by joining Cashmerette Club All Access, our yearly subscription. As an All Access member, Fitting University is included for free, and you’ll still keep lifetime access to it even if your Club membership ever lapses. Plus you’ll get access to our 50+ sewing patterns in sizes 0-32, monthly live events and fit clinics, and more!

Learning to fit clothes to fit my body totally transformed my relationship with getting dressed – and ultimately, with myself. I can’t wait for you to experience the same!
