Not vintage just something you've had for years.
I have a jumper I had at school and it still has a name tape sewn - it's 23 years old and worn regularly. It's a plain red hand knitted cotton jumper.
I also have two navy blue t-shirts that I've had for at least 25 years - I wore one the first time I kissed a boy - they are just thick cotton but amazing quality and have a very flattering sleeve length and hold their shape. I wore one yesterday. No idea what brand they were.
I also chucked some socks two years ago that my mother and I had both worn regularly - I nicked them off her - she bought them in Argentina in 1978.
