Work - suit in dark blue or grey with white or blue shirts and assorted ties. Often a wool blazer instead of a suit jacket to conform to the history teacher stereotype.
As soon as I get in - battered old hockey hoodies and shorts or 'loungepants'. Pyjamas, more or less.
Weekend - jeans or chinos, brogues, shirt or tee. Unless I'm playing hockey or out walking, in which case it's obvious.
I haven't yet the money to splash out to much on clothes while I'm squirrelling away money towards summer holiday travelling and a house deposit. My clothes seem to be from a mixture of Austin Reed, TM Lewin, Debenhams, Levis, TK Maxx, ASOS (online) and M&S.
