Size charts don't travel. Ella does. Your fit profile, built on real body science, that follows you across the internet - so you always know your size, wherever you end up.
How it works
01 — Answer
Height, weight, how you like things to fit. No tape measure. No complicated measurements. Ella does the rest in seconds.
02 — Match
Your answers are matched to a digital twin — a body model built from thousands of real, anonymised profiles. The science runs deeper than any size chart ever could.
03 — Shop
Ella travels with you across every brand, every website. She reads each garment and tells you your size before you buy — and gets sharper every time.
The plugin
Add Ella to your browser in under one minute. From that point on, activate here on any product page in one click. Try it in the demo! She reads the garment, including fabric, cut, brand sizing history, and cross-references your digital twin to surface your size, right where you need it.

Behind every recommendation is a body model constructed from thousands of real people's measurements — anonymised, aggregated, and continuously refined. Ella matches you to that model, then maps it against each garment's fabric, cut, and intended fit. Not an algorithm guessing from a brand's outdated chart. Body science, working quietly in the background.
What Ella learns from you strengthens the model for everyone — and what the model knows makes your recommendation more accurate than anything a size chart can offer.
