These are fantastic unisex joggers from Von Sono - a London based brand with sustainable design & production at its heart.
They can still be found online here: https://www.vonsono.de/collections/bottoms/products/copy-of-wide-elastic-joggers
These are a good fit for a UK10. They're high waisted and long in the leg so would suit slightly taller women... I'd say from 5'5" and up.
The fit is loosely fitted.
100% organic cotton jersey.
In fantastic condition - barely worn.
