As long as the clothes still look good as new then I will buy them, it's easy to wash them anyway. I think 2nd hand shoes are the ones that I won't purchase, because that looks and feels germ infested to me.
I wore hand-me- downs of my elder male cousin when I wan younger because my family was poor. I am appreciated for it. Now I have my own family and I sometime buy used clothes that suits me and whit goo quality. Actually I buy used pieces in good condition. It doesn't matter for me.
