Is there anything you have always worn for 25 years?
I had my first pair of platform boots for my 16th birthday (November 15th 1993) and now I've had a new pair of platform boots for my birthday this year. I have had them for my birthday in more or less every year in between, regardless of whether they are currently fashionable or not (as it happens they currently are). My new ones look like these:
I'm not old enough to have worn something for 25 years but I do have jewelry that was passed down to me that I've worn that is older than I am if that counts lol.
I had a friend at college who had a very similar pair, the first time around (1972) lol. I still wear a pendant the ex-love of my life gave me - and I've not seen her since 1989 ;-)
