Like pets, you can tell a lot about a person from their office jumpers.

Or jackets, shawls, gloves or any other item of festive wear (so as not to discriminate) for that matter, particularly on Fridays.

Offices are rarely the perfect temperature (maybe it’s a conspiracy) – in winter it’s always too warm, and in summer the air-con definitely makes you regret not bringing in that embarrassing but super-warm top. And don’t even get me started on spring and autumn – what a game of roulette that is.
