I've got a pack of seemingly nice quality t-shirts that got a lot shorter and wider after first wash.
I tried stretching them back to their original form but that doesn't work.
Used to be the cheap "three pairs for 10 euro" socks lasted a couple of years. Now I get, maybe, a year out of them before the holes get too obvious.
And price is not a reliable indicator of quality. Buying expensive can be just as much as a gamble as buying the cheap stuff.
"May shrink on first washing" or something like it seems to be pretty common; you might've accidentally tried something on which had that labelling (or didn't, which would suck).
