Do you have an old hat that's 15 years old but you can't give it up?
Or is it a suit you've worn to church for years or a decade?
For me it's my pair of dress shoes I pretty much only wear to church. I've kept them shined and don't wear them in snow, etc. and I've had them for about 10 years I think. Still look fairly new (the tread on the soles is gone).
