How to see clothes on yourself before you buy them

This is the practical version. How the generation works and why online clothes fail are covered elsewhere on this site. What follows is the sequence to run, from the photo to the order, and what to trust at each step.

Step one: the photo, which is most of the work

Every try-on you generate is built on one photo, so it is worth two minutes of care. The image the model needs is a boring one; it is an input, not a portrait.

• Full length, feet included. The single most common mistake is a photo cropped at the thigh. Without your legs the model guesses your leg length, and every hem, rise and coat length it then shows you is a guess about an average person.
• Plain background. A blank wall, a door, a curtain. Not a wardrobe with clothes in it, not a busy street. The edge between you and the room is where soft, melted-looking results come from.
• Natural stance. Square to the camera, weight on both feet, arms relaxed and a little away from your sides, hands empty. No crossed arms, no hand on hip, nothing in your pockets.
• No other people. One person in the frame. A friend half-visible at the edge confuses which body the garment belongs to.
• Even light. Face a window, or stand outside on an overcast day. Avoid direct sun, backlight and flash.
• Something fitted. A t-shirt and jeans or leggings. A big hoodie hides the shoulder line and waist the model needs to see.

Prop the phone at hip height about two metres away and use the timer. The photo guide has the reasoning behind each of these; the list is enough to get it right.

Step two: put the garment on yourself

In Utopia the photo builds a fit model once, and after that any piece in the catalogue goes on you in roughly a minute. The catalogue is real stock from around 277 brands; the brand pages list what is there and how each brand tends to fit. If you are choosing between two or three candidates, generate all of them, and save the ones that work. The saved image is the thing to send to a friend, which beats sending the product photo, because the product photo shows the garment on someone else.

Step three: read the image for what it can tell you

A generated try-on is a photograph, and photographs answer visual questions. Be strict about which those are.

The try-on answers shape and colour; it does not answer number or feel. Shape and colour are what people mostly get wrong ordering blind, so it removes most of the risk, but none of the sizing risk, and a convincing image should not persuade you otherwise.

Step four: pick the size separately

Once the try-on has told you the shape works, choose the size the boring way. Measure yourself once (chest or bust, waist, hips, inseam) and compare against the listing's size chart, or better, its flat garment measurements. If the listing gives pit-to-pit and body length, lay out a piece you own and love, measure it, and compare. Two numbers is enough for a top; rise and inseam for trousers.

Brand habits are stable and worth knowing. Uniqlo cuts to a Japanese block and runs short in the body. COS builds in room. Rigid Levi's feel a size tight on day one. The brand pages carry these notes because they are the kind of thing you only find out after the return.

Step five: use the returns policy as a backstop, not a plan

Ordering three sizes to send two back works until it does not: the window closes, the item was final sale, the refund is store credit, or the event was Saturday and the parcel came Monday. Try-on lets you order once; the returns policy is for the sizing miss you could not see, not the shape miss you could have.

1. 01Before ordering, read the return window and whether the item is final sale. Occasion wear and swimwear often are.
2. 02Check whether returns are free or paid, and whether refunds go to your card or to credit.
3. 03Count back from any date you are buying for. Delivery plus a possible exchange has to fit before the event.
4. 04Order the one size the chart points to. If you are genuinely between sizes and the piece is returnable, order two sizes of one item, never one size of three items.
5. 05Try it on the day it arrives, keep the tags on until you decide, and start any return the same week.

Trying on something from any store

If the piece you want is not in the catalogue, copy the link to its product page from the store's site or app and paste it into Utopia. The app fetches the page, pulls the main product image, and treats it as a garment you can put on your fit model like anything else. It works for most shops because nearly every product page publishes a primary image in a standard way for social previews; that same image is what gets used.

Two things make it work better. Paste the link for the specific colour you want, since many stores use a different URL per colourway and the image follows it. And prefer a page whose main image shows the garment on a body or laid cleanly flat; a lifestyle shot with the piece half-hidden behind a bag gives the model less to work with. If the page has no usable image, the app says so rather than inventing one. This is also the route for a piece a friend has sent you, a marketplace listing or a small brand no aggregator indexes.

The whole routine, in under ten minutes

1. 01Take one full-length photo against a plain wall in even light, arms slightly out, nobody else in frame.
2. 02Generate a plain t-shirt to confirm the photo is good.
3. 03Search the piece in the catalogue, or paste its link. Generate the two or three you are choosing between.
4. 04Judge silhouette, hem, drape and colour from the images. Ignore what they seem to say about size.
5. 05Pick the size from the chart or flat measurements, using a garment you own as the reference.
6. 06Read the return window and final-sale flag, then order one.

For an idea of what the results look like on other people before you take your own photo, the gallery shows looks made from real catalogue pieces, with the garment linked under each one.

Take the photo once. Then see the piece on you before you decide.
