About Rendered Fits

One product, three shopper questions

Rendered Fits helps a shopper explore how apparel might look, which size is suggested and which catalogue pieces go together. Merchants configure the experience on their Shopify product pages and can evaluate activity through merchant reporting.

The service is built for fashion stores evaluating sizing and visual product presentation. Current app availability, permissions and billing are shown in the official Shopify listing.

Rendered Fits is founded by Sydney and Sienna Stones. Product and merchant enquiries can be sent to mail@renderedfits.com or through the contact page.
