Mine is a black cashmere crew neck that I bought in a store near the British Museum in 1969! I have worn it all through the years -- it still fits well and is in good shape, and is still a favorite sweater among my dozens of black sweaters. I also have a Laura Ashley jumper that I wore to my son's 4th birthday party (he is about to turn 22) but I haven't worn it at all since then -- I keep it as a relic. Have had my diamond eternity band for 25 years -- and it was an antique when I got it. What's your oldest, much-loved item?
