Questions merchants ask

What is virtual try-on?

Virtual try-on creates a digital preview of a shopper wearing or using a product. Rendered Fits uses a shopper photo and existing product imagery for an AI-generated apparel preview. The image illustrates appearance; it is not a physical fit test.

What is the difference between AR and AI try-on?

AR often places a digital object in a live camera view. Generative AI try-on creates an image from inputs such as product photography and a shopper photo. These labels cover different implementations, so compare the actual output and input requirements.

How accurate is AI virtual try-on?

Visual realism and sizing accuracy are different. Check garment shape, colour, pattern and image artefacts on your own product examples. Evaluate size recommendations independently against product information and fit feedback. We do not publish a universal accuracy percentage.

Does virtual try-on reduce returns?

It may help address uncertainty about appearance, while size guidance addresses size selection. The effect on returns must be measured for the store using mature order outcomes and a fair comparison. Rendered Fits does not promise a fixed percentage reduction.

Can virtual try-on increase conversion rates?

It may help a shopper evaluate a product, but a purchase after try-on does not prove that the app caused the sale. Compare eligible traffic using a suitable controlled test where possible, and report observational results as associations.

Which products should I test first?

Start with a small set of apparel products with clear imagery and reliable sizing information. Include a straightforward example and a more demanding one. Confirm category suitability before rolling out, especially for unusual materials, layering or accessories.

Is virtual try-on the same as size recommendation?

No. Virtual try-on previews appearance. Size recommendation uses shopper inputs and available product sizing information to suggest a size. Rendered Fits combines both, and neither guarantees fit.

How much does Rendered Fits cost?

Rendered Fits has an ongoing Free plan and optional paid plans. Eligible merchants can also receive a separate paid-plan trial. The pricing page and Shopify billing approval show the current prices, processing allowances and terms.

What is the best Shopify virtual try-on app?

The right choice depends on your product category, shopper workflow, sizing requirements, budget and integration. Compare current vendor information and test the same products across shortlisted apps. Our sourced comparison explains the differences without declaring an untested winner.

How should luxury brands evaluate try-on?

Evaluate whether the output preserves product details and whether the experience suits the store presentation. Include difficult fabrics and patterns, mobile usability, sizing information and support. A premium brand position does not establish that one app has the best output.

How does Rendered Fits work?

Shoppers can preview apparel on a photo, receive a product-specific size recommendation and explore coordinating pieces through Complete the Look. Merchants install the Shopify app and configure eligible products and theme placement.

How do I install Rendered Fits?

Install through the official Shopify App Store listing, review the plan and permissions, follow the app setup, choose products and enable the theme placement. Test photo input, recommendations and cart behaviour before publishing the experience.

How long does setup take?

Setup depends on the theme, catalogue and readiness of product information. Test a small selection before planning a wider rollout, and contact the team if custom theme placement or imagery needs attention. We do not guarantee a fixed setup time.

Does it work on mobile?

The shopper experience is designed for product pages viewed on mobile and desktop. Check your actual theme, photo input, result display, variant selection and cart behaviour on the devices your customers use.

What should I check about photo privacy?

Read the current shopper privacy notice and merchant terms before enabling the experience. Check what is collected, why it is processed, the applicable retention terms and how requests are handled. Do not infer a privacy guarantee from an image demonstration.

What happens to a shopper photo?

The current privacy notice explains image handling and retention. Follow that notice and the available request process for specific questions; this FAQ does not replace the policy or promise deletion at the end of a session.

Where can I verify Rendered Fits?

Use the official Shopify App Store listing, its public merchant reviews, the product demonstration and the company contact page. Our evidence note distinguishes merchant feedback from measured performance claims.
