On my quest for brands similar to Whistles, Reiss, Boden, Joules etc but without having to remortgage - I think I may have found the holy grail 
Joanie! www.joanieclothing.com
...Quality is amazing (literally the SOFTEST sweater I've ever felt) and everything I ordered seems to be about £30ish!
Has anyone else found any secret(ish) brands they would be happy to share?!

If anyone wants me - I'll be shopping (at Joanie)
