Is it unreasonable to sell hand me downs?

Would you feel it was cheeky to see your hand me downs on Vinted? It's weirdly making me feel sentimental/pissed off.

I'd rather have them back to pass on to someone else in need. I passed them on thinking I was helping

If you had wanted it back after they were done with it you should have said so.

Didn't want them back really but would have liked them handed on/given to charity. Seems odd to make a profit from hand me downs
