Bought these Zara linen trousers three weeks ago from TK Maxx. I wore them for 2 days, chucked them in the wash (30c, low spin, line dry) and have just noticed that the seam is split. So annoying - they cost a tenner but that's £5 per wear, plus more landfill 
I've literally never taken anything back to TK Maxx on quality, I feel like they'll just tell me to bugger off. But I do find it infinitely annoying.
Unreasonable to take them back?
So fed up with the quality of everything being shit.
