Just thinking about it I have no visible logos on me a the minute, if I take my jumper off the T shirt I am wearing has a big carhartt Logo made up of pictures of robots I think, 90% of people couldn’t actually Identify the brand from it I reckon…
It’s not actually Very dificult to be “Brandless” in your day to day clothing but normally wearing branded clothing goes beyond simply turning yourself into a “Walking Advert” as you put it…
In Marketing BS it’s often the case that something about a brand/company image and/or their product semantics appeals to you, you identify with the Brand in some way and are effectivly displaying a sign of your identification with said brand….
And you paid for the Privilege You Mug!!!
If it really upsets you that much why not just shop at M&S with all the other old Giffers….
