Virtual try-on: what it is, how it works, and why it matters for your brand.

Virtual try-on lets a customer see a garment worn on them before buying it, straight from a product page. It relies on a 3D digital twin the visitor creates from their height, weight and body type, plus their measurements if they want more precision.

It changes the very nature of the purchase: customers no longer order a garment blind, they order a garment they have already seen on themselves.

What is virtual try-on?

Virtual try-on (or a virtual fitting room) is an experience embedded in a fashion store's product page: the visitor sees the garment worn on a silhouette that mirrors their own, instead of guessing from photos shot on a model who looks nothing like them.

It is the online answer to a reflex everyone has in a physical store: stepping into the fitting room before paying. E-commerce removed that step; virtual try-on puts it back, at the exact moment the customer hesitates.

How does it work in practice?

On the product page, everything fits in three steps for the customer:

• They create their 3D digital twin: height, weight, body type, and their measurements if they want to fine-tune. No photo to upload.
• They see the garment worn on them, accurate to the centimeter, from several angles: front, side and back.
• They get their recommended size for that specific product, with a fit description.

Visualization and size recommendation work together, on the same integration: customers see themselves, then they know what to order.

What it changes for a fashion brand

Doubt is the last brake between a product page and a cart. A customer who has seen the garment on themselves and knows their size has no reason left to hesitate, or to order two sizes “to compare”, which fuels returns.

The experience stays fully in your brand's colors: it blends into your store, your product pages and your identity, with no redesign.

How OptiDress addresses this

OptiDress is a virtual fitting room: the visitor creates their 3D digital twin from their physical characteristics, without uploading any photo, sees the store's garments worn on them and receives for each product a size recommendation with a fit description (OptiSize). The avatar is kept for 30 days on the store.

Integration is performed by the OptiDress team, from Shopify to custom-built sites, using your existing visuals and your garments' real data. No new photo shoot is needed, and the subscription has a plan based on try-on volume, decreasing overage rate, no commitment.

The simplest way to judge is to try it: the Maison Léon demo store replicates a real fashion store with the full journey, from the 3D digital twin to the recommended size.
