Clothes you can't get rid of .

So I have a lot of clothes. Not because I go shopping often , because I take good care of my clothes. Atleast my non work clothes.
So last night I went to a friend's for a birthday jam and party.( jam for the uninformed play music with other musicians.
So my friend is a character and we always have a blast.
I have an old shirt from my younger clubbing days. It is shiny and looks like a 70's disco shirt.
I decided it would be perfect for the occasion!
Lol it was a real crowd pleaser !.
I knew it would bring smiles and laughter
Many times I almost threw the shirt out along with a bunch of others. I just could not do it.
I have not worn the shirt or a few others for 20 or more years. I'm glad I did not throw it out !
I'm pretty sure there will pictures circulating now in my disco shirt.
People even wanted to buy it. Lol
What clothes or clothing can't you seem to throw out ?
