About Sizible
Sizible uses AI and smart technology to suggest the correct fit every time.
Happier shoppers, fewer returns.
Born from Frustration. Built with Purpose.
Our founder, an experienced fashion designer, faced chaos designing 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 shopping. The same size varies by up to 6cm across brands. Generic size charts don't work, leading to hesitation, returns, and clothes we don't love.
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 specific brands actually fit, offer personalised style advice, and show how clothes will look on their body type before they buy.
We believe everyone deserves clothes that fit,
retailers deserve confident customers, and returns
shouldn't be inevitable.
