Kat is a Blogger and Wardrobe Consultant & Personal Shopper. She have a, perhaps, unhealthy obsession with fashion and have just realized that at 40 it appears that one is supposed to wear gilets and raincoats with "fun" linings.This is the journey into her 40s hunting to find a style that doesn't scream mutton or frump.
