Or, more seriously - I'm looking forward to getting back on a Brompton at the start of April. As usual, I'll be simply wearing work clothes. For my first few years of commuting I wore jeans and a tshirt and changed when I got to the office. Then I switched to lycra, but I quickly realised that the ride was fairly short (about half an hour) and I didn't get sweaty enough to worry about changing. I simply change when I get home.
