Virtual Try-On vs AR Mirrors vs Photoshop: Which One Shows the Fit?

There are three ways to see a garment on a body before you own it: an AI try-on from two photos, an augmented-reality mirror that overlays a 3D garment on a live camera feed, and a retoucher with Photoshop. They look similar in a marketing screenshot and behave completely differently in practice.

The three options side by side

The practical difference is the first row. An AR mirror needs a 3D model of *that specific jacket in that specific colourway*, which is why it lives on retailer apps and flagship stores. An AI try-on works from any product image you can find, including a screenshot of a second-hand listing.

What AI try-on genuinely gets right

• Silhouette and volume. Whether a coat swallows you or a blazer cuts a sharp shoulder is a shape question, and shape survives the translation.
• Colour against your skin and hair. The most common reason a purchase gets returned is a colour that looked different on the model. Your own photo fixes that in one step.
• Length and proportion. Where a hem lands on your leg, where a sleeve ends on your wrist, whether a midi reads as maxi on your height.
• Combination. Whether the item works with the trousers and shoes you already own, which no single-product page can answer.

Where it stops being reliable

This is the part most tools skip. A generated preview is a picture of a plausible outcome, not a simulation, so treat these four things as unknown:

1. 1Fabric weight and drape. A 400 gsm wool coat and a 180 gsm polyester one can render almost identically. The preview does not know the difference unless the source photo shows it.
2. 2True fit at the seam. Whether the shoulder seam sits on your shoulder depends on measurements, not pixels.
3. 3Small construction detail. Stitching, beading, print alignment and logo placement are the first things to drift at the edges of a generated image.
4. 4Exact colour under your lighting. The preview is correct relative to the garment photo you gave it. If that photo was colour-graded, so is the preview.

AR mirrors are not the same product

An AR mirror is a rendering problem solved by the retailer: someone modelled the garment, so the overlay is geometrically anchored to your body and moves with you. That is more accurate in motion and far narrower in coverage. It also exists to reduce returns inside one store, not to let you compare five stores before lunch.

Photoshop still wins on one thing

Control. A retoucher can place a seam exactly where you ask, match a specific lighting setup, and produce a file at any resolution. What it cannot do is run at the pace of a shopping decision: by the time the composite is finished, the sale is over and the size you wanted is gone.

A workflow that actually saves money

1. 1Shortlist three to five items from any number of shops.
2. 2Preview each on the same person photo, so differences are the clothes and not the pose.
3. 3Eliminate on shape and colour first — this is the cheapest filter and the one previews are best at.
4. 4For the one or two survivors, check the size chart and measure yourself.
5. 5Only then look at construction details in the product photos.
