I mean why not?

Do it. A knock off is better than none :)

I have an anko Kmart one and its fine

I bought the Minipeelers knockoff oodies and matching pants from the qvm, plus just the pants for myself, about 2 years ago. They are holding up brilliantly, so well that they look like they were purchased more recently. Can’t vouch for the ones they’re selling atm, but I’m very happy with the ones I got.
