Just to throw a wrench in -- I have a striped tee from Zara from years ago (2015~) and it is still completely pristine and has been worn a LOT. A heavier cotton, oversized bloused fit that seems as on trend now as it was when purchased. Also a white tee with foil accents -- it looks as good today as when I bought and I have worn it a lot.
But I will agree, their tees vary. I have ordered a lot only to send most of them back. You just can't tell from the image or description.
Oh, and I will add -- I only wash the foil tee on delicate, no dryer, and while the striped one goes in the washer I don't think I have ever dryed it in the machine, either.
