The skills YOU need to fit and flatter

As a sewist with a belly I struggled with fitting until I took sloper school. It changed my sewing forever and prepared me to understand Susan Khaljes masterclass on the Elmwood skirt. Now the clothes I make fit and flatter with professional finish!

Clothes that are me (at long last!!)

As a curvy woman, I've found it impossible to find styles of clothes I liked in the size I need. Completing the Wyman Sloper has taught me to understand my body shape and reflect the extra length of my torso. It's boosted my self confidence and helping me find my true style.

Fitting Assumptions Debunked and Confirmed

At 5 feet 1 inch and a short waist, I routinely shortend the waist to hip line of any skirt or pants pattern according to my measurements. I made the sloper and discovered that is not correct, I actually need to add a bit of length. I haven't figured out how that all works out yet but I got a great fit from the sloper! I also confirmed that my upper body (shoulders and neck) are a great fit from a size 10, no changes needed.

A great fit every time

As a trained dressmaker I could sew anything but fitting was all guesswork and not always successful. I have narrow shoulders and upper bust, large boobs, wide back, short arms and short legs, plus I am pear shaped. With the help of Sloper School and the Fitting University I made the Wyman Dress Sloper which I use to guarantee a perfect fit every time by using my own fitting information and Jenny's clear instructions to adjust patterns and also create my own patterns. My clothes now fit my unique body at last.

Breakthrough in sewing, so I don't break through my clothes!

As a mostly self-taught sewist with proportions outside the "norm" (E cup bust, long torso/short legs, and a bit of a belly, to name just of few of my quirks), I have long struggled with sewing things that fit me properly. Using ready-made patterns was almost as bad as buying a garment from a store. I didn't know what was wrong or how to fix it. After going through the sloper school, I found I finally understood where my measurements were different, and how to change them, whether on store-bought or self-drafted patterns. Jenny's instructions were clear, concise, and easy to follow along with. My me-mades have never fit better!

Details matter & club access nails it!

The best combination to learn how to sew well fitted clothes is to combine Cashmerette's Club Access with their incredibly well-designed curvy patterns. I struggled with getting a basic well-fitted top before I took the Wyman Sloper School (free for Club members). The learning is carefully spoon-fed to you through the online videos, the community forum, and the actual sewing. The best part is being taught how to evaluate your changes in your muslins. The well-thought out steps even got me to have sleeves that aren't covered in draglines! After all this learning, I was able to sew a perfectly fit Vernon shirt (collar, sleeves and all!).

Busty baddie breaks beyond basics

I have a very large chest, short torso, and full booty. I hated how awkward anything woven fit me, so I just stuck to very loose fitting clothes or knitwear. I took the Wyman sloper course and FINALLY learned useful methods for my exact fit issues: full bust adjustment, swayback, and full booty adjustment! I also learned a few other fit issues that I had never even thought of, like a sloped shoulder adjustment. I still don't do all these on every pattern, but now it's not because I don't know how. I've been LOVING going through my woven fabrics and not being afraid that they'll be wasted on a bad fitting project. The course is so clear about diagnosing and adjusting that i wasn't intimidated. I love that they show real examples on people instead of just talking about what to look for. This class is seriously invaluable for the voluptuous baddies out there

Button down dress? No problem!

I haven't owned an article of clothing that buttons down the front for decades; now I have a lovely summer dress with 14 tiny adorable buttons!! It's a result of taking the sloper course, and being confident that I could make it fit! Biggest surprise for me was that I needed a narrower shoulder, even with my big boobs.

A sloper that fits me!!!

As a petite and plus size sewist with big boobs, I've struggled for years with getting fit right. I found fitting each new pattern I want to sew from scratch or a few key measurements time consuming, exhausting, and never very effective the first time. And I've tried drafting my own blocks several different ways, but nothing has ever works for my type of shape. Cashmerette patterns have always been the best patterns for me, but usually I always had the best fit with their knit patterns. Frankly, I've had fit issues with their woven patterns so I was wary to give their sloper school a try. But I'm so glad I did! I really like how the class was broken down into manageable steps. And the sloper actually fit really well right out of the packet! The video chats about fitting with real people with Jenny helped soooo much. Seeing what the same fitting problem looks like on different bodies really helped me understand what to look out for more. And there were some hidden fitting gems I found that really worked for me, like how I needed length out of back bodice and was able to make that just disappear into a larger from dart so the side seams match. Mind blown! With the sloper, I'm able to overlay it on a new pattern I want to try and right away figure out what size to cut and what adjustments I need, much more than I tell could before. I personally struggle a lot many fitting issues that sometimes compete with each other. Like a short upper body, but large bust and high round upper back. Narrow shoulders, but large biceps. So the sloper has helped me get new patterns to fit well the first time, and I'm not afraid to cut into the good fabric on my first try of a new pattern, whereas before I'd always need 2 toiles before. 1 muslin and then 1 wearable muslin before cutting into my final fabric. Also, I've been able to draft patterns from scratch from my block, which has been really fun and easy. With all the confidence I've gotten from this class, I finally got the courage to start working on my pants fitting journey. Which is a whole other battle, but I feel like the foundation of fitting knowledge from sloper school along with the momentum of a sloper that finally fits, gave me the confidence to work on the next step of my fitting journey which I've put off for nearly a decade. P.s. that's also going well 🤗
