I like this Stella McCartney version of a mac. But if I am going for something practical, perhaps that should apply to the price tag too
A classic, shiny slicker in a bright color could be fun. No reason to try and go too fashion-y (I am in the suburbs, after all).
P.S. Who knew TopShop had online shopping?
Does anyone have a good (relatively stylish) solution to dealing with the rain?
