Born from Frustration. Built with Purpose.

Sizible founder Aideen
Aideen — Founder

Our founder, Aideen, an experienced fashion designer, faced chaos designing bespoke uniforms for a pan-European airline — sizing varied wildly across regions, the same size fit differently across body types, and coordinating measurements was a nightmare.

Her conclusion? The sizing system was broken.

That frustration became a mission: fix online fashion sizing.

Our tech co-founder got to work. Together, they built Sizible — bringing in-store confidence to online shopping through AI-powered personalisation.

We match customers' unique measurements to how brands actually fit, offer personalised style advice, and show how clothes look on their body type before they buy.

Everyone deserves clothes that fit, retailers deserve confident customers, and returns shouldn't be inevitable.
