Virtual try-on for fashion: a beginner's guide
in fashion, virtual try-on works better and is more mature for accessories (glasses, caps, jewellery, watches, bags) and footwear; for clothing, there are solutions that simulate garments on an avatar or on an image, with more complexity and variability. The sensible approach is to start with the simplest categories that have the greatest impact, and expand afterwards.
What can be tried on in fashion
Accessories
- Sunglasses and frames: the most established case.
- Beanies, caps and hats.
- Earrings, necklaces and bracelets.
- Watches.
- Scarves and neckerchiefs.
Footwear
Foot tracking with the phone camera, so the shoe can be seen on the user's foot. Useful for seeing style and how it pairs, although it does not solve size.
Bags
Visualisation at scale on the body, or placement in the space with AR to see the size.
Clothing
There are several approaches:
| Approach | How it works | Advantages | Limitations |
|---|---|---|---|
| 3D avatar | The user creates an avatar with their measurements | Approximates size and drape | Less "myself" |
| Overlay on an image or video | The garment is placed over the photo or the camera | Immediate visual | Less accuracy of fit |
| Digital model in 3D | The garment is shown on a mannequin or a model | True to the product | Does not reflect your body |
| Smart mirror | A screen in store | Striking experience | Requires hardware |
What problem it solves
In fashion, the most common reasons for returns tend to be size/fit and looking different from what was expected. Virtual try-on mainly addresses the second (how it looks on me aesthetically) and, with avatars and size-recommendation tools, partly the first.
When it is a good idea
- Accessories, where the face or the body defines the purchase.
- Products with many variants of colour or model.
- Brands that want to differentiate through innovation.
- Launch campaigns for collections.
- Physical store, to extend the range without stock.
How to prepare the catalogue
- Prioritise the best-selling products, or those that raise the most doubts.
- Gather materials: photographs, measurements, technical designs, physical samples.
- Create the 3D models (often starting from patterns or a scan).
- Define variants: colours, sizes, finishes.
- Optimise for web and mobile (guide).
- Test with people of different features and skin tones.
Experience design considerations
- Visible button on the product page.
- Clear instructions ("Allow the camera and look straight ahead").
- Capture and share to generate virality.
- Fast switching of model.
- Immediate link to purchase.
- Inclusivity: test with a diversity of faces and lighting conditions.
Measurement
Record uses, try-on time, the most tried products, conversion among those who use it, and returns by category. See how to measure virtual try-on performance.
First steps
- Choose a pilot category (for example, glasses or jewellery).
- Select 10-30 references.
- Launch on the web with a try-on button.
- Measure for 4-8 weeks.
- Expand according to the results.
Key ideas
- Accessories and footwear are the simplest to implement.
- For clothing, the solutions are more complex and variable.
- Start with a pilot with few references.
- The quality of the 3D model determines credibility.
- Measure use, conversion and returns.
Frequently asked questions
Does it solve the size problem?
Not entirely. It helps with the aesthetics; for size, recommendation tools or avatars are needed.
Is a 3D model of each garment needed?
For most approaches, yes, or an equivalent digital representation.
Does it work with all kinds of skin and faces?
A good solution must be tested with diversity. Ask for examples and tests.
Can it be used in a physical store?
Yes, with smart mirrors, screens or the customer's phone.
