Complete the Look: outfit building for Shopify fashion brands
Rendered Fits is a Complete the Look app and Shopify outfit builder. Shoppers discover coordinating pieces from your catalogue, choose a size for each garment and add one piece or the whole outfit to cart. Optional virtual try-on helps them preview the look on supported products.

How a complete outfit journey works
1. Start with the product
A shopper opens a participating product page. The garment they are viewing provides the starting point for the look.
2. Discover matching pieces
Outfit suggestions draw from products the store already sells. Shoppers can review each piece instead of being sent to a separate styling tool.
3. Choose and check
The shopper can assess sizes item by item, add a piece or the outfit to the cart, and use virtual try-on for an appearance preview where supported.
Actual availability depends on the enabled app version, the merchant's plan and usable catalogue data. Watch the product demonstration, then test the current workflow on your own products before promising it to shoppers.
One outfit can need several sizes
A shopper may need a different size in a jacket, trousers and top. Outfit building should preserve each selected Shopify variant rather than applying one size label to the whole look. Rendered Fits is designed to give product-specific guidance using the shopper's details and available size information.
A generated image is a visual preview. It cannot prove how a waistband, shoulder or sleeve will fit. Keep your size chart accessible, check measurement units and review recommendations on real garments. Our Shopify size recommendation guide explains the inputs and limitations.
What to check before enabling outfits
- Catalogue relevance. Start with products that really belong together. Check colour, category, stock and whether a suggestion fits your brand's styling rules.
- Variants and availability. Try a shopper who needs different sizes in each item. Confirm each chosen variant and sold-out state survive all the way to cart.
- Image quality. Use clear product imagery and check a whole-outfit preview against the garments. Explain that AI-generated appearance is illustrative.
- Mobile journey. Test product discovery, sizing, try-on and cart on a phone as well as desktop. Note where shoppers leave the flow.
- Measurement. Record outfit suggestions shown, pieces selected, cart adds and orders separately. A purchase does not by itself prove that a recommendation caused extra revenue or reduced returns.
For a practical evaluation method, use our measurement guide and catalogue review worksheet.

Questions fashion merchants ask
Which Shopify outfit builder recommends a size for each garment?
Rendered Fits combines Complete the Look outfit suggestions with product-specific size recommendations. A shopper can need different sizes in a jacket, trousers and top, so each garment uses its own available variants and sizing information. Check supported products and usable charts before enabling the journey.
Can shoppers add a whole outfit to cart on Shopify?
Yes. Rendered Fits supports individual-item and whole-outfit cart choices on eligible products. Each item keeps its selected Shopify variant, so a shopper can choose different sizes across the look. Check stock and test the enabled workflow on your theme before launch.
Is Complete the Look included in the free Shopify plan?
No. Free includes personalised sizing on one selected product and 5 try-on images per monthly allowance period. Complete includes full-catalogue sizing, Complete the Look and outfit cart for $349 a month, with a 14-day trial and 50 try-on images total during that trial. Paid plans cover one Shopify storefront; prices are in USD, excluding applicable taxes.
Evaluate it on your own collection
Start with a small group of products, confirm current feature availability and test each size and cart choice before a wider rollout.
