Rendered Fits Alternatives
The Faslet Alternative for Shopify Clothing Brands
As featured in Vogue College of Fashion · The Jockey Club Style Awards
Faslet is a size and fit platform for fashion brands across Europe. Its Shopify app, Faslet Size & Fit, combines machine-learning size recommendations with a virtual try-on, missed-sales tracking and fit insights, and it has been on the App Store since May 2022. It is a serious product and one of the closest things on Shopify to what Rendered Fits does, so the comparison comes down to how each one is priced and what each one covers beyond the size.

Where the two differ
- How the cost moves. Faslet’s plan follows the number of shoppers who use it, so a successful season moves you up a tier. Rendered Fits is a flat monthly plan; the only extra is try-on images beyond the allowance, and only if you turn that on with a cap.
- Outfits, not just the item. Rendered Fits builds the rest of the look around the product, sized for that shopper, and lets them add one piece or the whole outfit to the cart.
- Built from your charts. We clean the size charts you have and generate the missing ones as part of setting you up. You keep them either way.
We are not going to promise you fewer returns. Nobody can promise that before they have seen your cohorts, and anyone who does is guessing with your money. What we will promise is on this page instead.
What Rendered Fits actually is
A Shopify sizing intelligence app for clothing brands, built to tackle the returns and lost sales that come from customers guessing their size. A shopper puts in their measurements, gets a bespoke size for that specific garment rather than a generic chart reading, and then has the option to see it on themselves before they buy.
