hmmmm... I'm interpreting this more as 'when will all these diluted brands waste away'.
I don't have an answer for that. As for T-shirts in general, I think it's beyond being the cornerstone for streetwear. They've been used as personal statements since forever; personal billboard, flier, etc are also applicable. They showcase who or what you affiliate yourself with in absolutely every aspect of that context (religion, politics, literature, blah blah), it's truly an infinite canvas of sorts. Can't say that about most other articles of clothing. The price point of tees are also a great incentive.... most times, at least. blah blah blah. My 2 cents: the value of the tee never went anywhere.
its hard to say,seem like the street wear hype is sorta dying
but i will,forever be in it as long as its here cause its not a trend for me
