Ok, I had two lovely lightweight (but still warm) jumpers last year. One from &Other Stories(size M) and the other from Mint Velvet (size 12). Both were the perfect wide shape and length to have shirts underneath, both were wool mix and both have been destroyed in the evil washing machine that lured me in with promises of a 'hand wash' wool cycle... 
I am back in London next week for 8 days, and only have a couple of hours free to shop. Would love some ideas of places to look for a replacement, or suggestions for something available online that I can order (and return if necessary) within that time frame.
Can anyone recommend a lightweight boxy jumper, size 12-14, possibly in grey/navy (but colour less important than style) please?
