Start with your size.
Select the size you want to try. You stay in control of what OnU shows you.
A size label can’t show where a hem lands or how a sleeve hangs. OnU lets you choose a size, see its expected fit on your own body, and understand the details before you buy.
Does the shoulder sit right? Where does the hem fall? OnU is built to visualize the size you selected on your own body, then explain the fit details that a size chart can’t show alone.
See the app flowFrom the item you found to a size-specific view and clear fit notes.

The chosen size shapes the preview. Fit notes help you read the details.

Don't just see the garment.
See the size on you.
You choose the size you want to see. OnU can offer a size suggestion, but the heart of the experience is showing how the selected size is expected to sit on your body.
The visual is a size-conditioned estimate based on your photos and available garment information. Fabric, lighting and the physical fit can differ in real life. The screenshots here show the current app with sample data; the demo result uses a placeholder figure.
