I take a lot of inspiration from various Asian street style blogs. I don't know if this is a good idea because what works on bright young things from Tokyo doesn't always translate to a middle aged English lady. It doesn't keep me from trying though.
Today I tried to sharpen up what is probably the most un-fashion item in my possession, a slouchy men's jumper from Scotland. I love this thing. The soft knit and rich colour scheme have a happiness factor that is off the charts, but there's no denying it looks bigger than it is, and that's being polite.
So, with the help of this picture of a willowy young man who seems thoroughly at home in oversized knitwear, I'm trying to convince myself that frumpy can be edgy and a chunky jumper works with a faux-leather midi skirt.
ETA with pic: I took your advice. Revisiting the look today with a sheer navy button-down shirt from American Apparel and my venerable DvN pleated skirt. I think this works much better. Thanks merwoman and avicennia for the suggestions.
