I am currently in my favourite Desigual dress which I wore to work today (school) . I wear it out too. First worn in 2006 ( in my staff photo) and every year since. It's a nice weight of cotton jersey so never looks too warm or too thin. Washes well in the machine .
Thick tights and boots for Autumn and Spring terms and with flats in the summer.
I suppose it will wear out eventually and I'll be bereft.
Whats everyone else got?
