How does AI virtual try-on work?
An AI try-on app takes two photos, one of you and one of a garment, and uses an image model to draw the garment on your picture. In Fake Flex, that takes a few seconds.
Get Fake Flex on the App StoreThe inputs
Fake Flex asks for four choices:
| Choice | Options |
|---|---|
| Your photo | One from your library, or a new one |
| The clothing | A product photo, a screenshot or an item laid flat |
| A pose | 10, including keeping your own and a runway pose |
| A photo shape | Portrait, square, wide, vertical or original |
What happens next
Fake Flex sends the photos to fal.ai, its AI provider, which runs OpenAI's image model. You get a new picture of yourself in the outfit. Fake Flex's App Store listing says the model draws fit, folds and fabric onto your own photo.
What it is and is not
Fake Flex gives you a generated image for a quick look at color, shape and style. It isn't a measurement. It can't tell you whether a size medium will fit, so use the retailer's size chart for that.
Other approaches
Some apps create a reusable AI likeness first. Doji's listing says you upload a few photos to create one, then use it to try on many products. Fake Flex skips that setup and works one try-on at a time.
Supported items
Fake Flex supports tops, dresses, jackets and pants. Pro members can try on up to 4 items at once.
Questions
Is the result a real photo?
No. Fake Flex returns an AI-generated picture.
How long does it take?
A few seconds. That's what the Fake Flex site says.
Where does the work happen?
On the AI provider's servers. Fake Flex uploads your photos and asks before the first upload.
