Rendered Fits Alternatives
The Virtusize Alternative for Shopify Clothing Brands
As featured in Vogue College of Fashion · The Jockey Club Style Awards
Virtusize has built sizing for large fashion retailers for over a decade, and in April 2026 it launched a self-serve Shopify app, Virtusize: Smart Sizing & Fit. The app shows shoppers a size recommendation and a body-based fit visualisation from a few simple inputs. It costs $1 for the first month, then from $39 a month for 200 orders, with per-order rates as orders grow.

Where the two differ
- A fit diagram or the shopper in the garment. Virtusize visualises fit against a body outline. Rendered Fits can render the actual garment on the shopper’s own photo, so the answer to “what will this look like on me” is a picture of them.
- The rest of the outfit. Rendered Fits adds Complete the Look and outfit sizing, with individual-item and whole-outfit cart, in the same app.
- How the cost moves. Virtusize’s price follows your order volume. Rendered Fits is a flat monthly plan with no sales-based fees.
When Virtusize is still the right answer
If you only need a size answer and your order volume is low, Virtusize’s entry price is well below our paid plans. If you want sizing, outfits and a try-on preview from one app, that is what Rendered Fits was built for.
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.
