Nothing as bad as some of you, but I do wear a grey long sleeved base layer that I've had for about the past 10 years.
I also have a collection of Hats, T-Shirts and Jumpers, and, I have stayed roughly the same weight since I was 15, so I can still wear various commemorative things at the next event/anniversary etc etc.
For example, I have a Glasgow Underground 100 years t-shirt from 1996 that I could still easily wear at the next big event they have, or the West Highland Line 100 years jumper from 1994.
