The size you chose, on your body

See how that size
looks on 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.

01 / The idea

The difference between sizes
is something you can see.

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.

02 / How it works

Your choice.
Your view.

From the item you found to a size-specific view and clear fit notes.

03 / What you see

A size is more
than a letter.

04 / Good to know

A few things
you might ask.

Does OnU pick my size for me?

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.

Will the try-on match the real garment exactly?

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. These illustrative screens use sample data and a fictional AI-generated model and garment; actual try-ons and physical fit may differ.

What happens when I join the waitlist?
