A fitting sloper is a basic, closely fitted pattern that you refine until it fits your body really well—and then you can use it to adjust other sewing patterns to fit you without endless rounds of muslins, or you can use it to create infinite different looks through hacking techniques.

Sloper School opens for enrollment during limited timeframes during the year. Once you join, you can take the course at your own pace, and you have lifetime access to all the materials.

In Sloper School, you’ll learn through a mixture of recorded video lessons, written tutorials, and personal feedback from the Cashmerette team. You can access the curriculum any time, do it at your own pace, and skip directly to the parts that are relevant for you, so no matter your schedule, you can participate.

This is a great course for all sewists looking to improve their fitting, who already know how to sew garments - you’ll need to know how to sew a woven dress with a zipper and set in a sleeve.

Yes! Sloper School is designed for sewists who are working solo from home. But with the Cashmerette team here to help, you'll never feel alone in your fitting journey!

Sloper School is a totally different approach to fitting. In Sloper School, I focus on one fitted, woven dress and work through all the relevant fitting issues, before then teaching you how to use your sloper to adjust new patterns quickly and easily, and hack it into other designs. It’s an intensive, deep-dive into a specific fitting approach. Sloper School includes lots of demos on models with different body shapes, and unique workbooks that you’ll progress through.

Fitting University is a online fitting course that covers all types of garments, which you can dip into any time that you need. Unlike Sloper School which you work through from beginning to end, Fitting University is more like a fitting reference library that you can refer to as you’re sewing any garment.

The great news is that if you join Cashmerette Club as an All Access member you’ll have FREE access to both Fitting University and Sloper School!

This course is open to everyone! You can enroll in Sloper School with a one-time payment.

But if you're a Club member, it's even better! Cashmerette Club All Access members can enroll for FREE, and get lifetime access even if their membership expires.

All Access is a yearly auto-renewing membership, but you can cancel any time .

Yes, the course is entirely online and open to anyone around the world!

We’ve worked hard for over a year improving and revising Sloper School based on student feedback! The biggest changes for 2026 are:

• It’s now self-paced. Instead of having to be available on certain dates, you can now go through the course whenever you want. Linked to this change, we will no longer have Live Fit Clinics as the vast majority of our students weren’t able to attend them.
• Get all the lessons, instantly. Previous Sloper Schools rolled out lessons on a week by week basis, which meant some students had to wait until a relevant topic was covered. Now, all the videos and lessons are available instantly so you can go straight to what you need.
• The process to create your first muslin is totally revamped. We’ve created a brand new approach using a clear flow-chart method which takes you step by step through exactly what you need to do to create a well-fitting first muslin.
• The feedback process has improved. You can now get 1:1 feedback from the Cashmerette team in a clearer, streamlined, and totally private way.

To participate in Sloper School, you need to be able to sew a woven dress with a zipper and set-in sleeves, and be able to take digital photos and upload them to the feedback form (any smartphone can do this!). In addition, you’ll need:

• An internet connection that can stream video
• A computer, tablet or phone to watch the videos and submit questions for feedback (note, we strongly recommend downloading your pattern to a computer, not a mobile device)
• The free Adobe Acrobat program (downloadable here for PC or Mac)
• Access to a home printer, printing service or projector
• The sewing equipment to sew a woven dress
