Really? Since when? Thats what the base of streetwear has and will always be. People wont stop wearing t-shirts and hoodies. It's wearable art. What do you want new brands to do, come up with some new type of clothing article? You want every brand to do cut & sew, then people will be complaining that no one is doing t-shirts and hoodies.
My nigga, I think you stopped reading after my second paragraph.. My point is that the Story is missing from streetwear. The soul of the brand. I'm a humble student to the game and see brands sprout all the time with no roots. Just a plant hovering above ground with no root to prevent the wind from blowing them over. It goes well above streetwear.. you need an iron string, a cause, a source that connects to something real, then from that you birth the creation, the art, the graphic tees, hoodies, cut n sews, nigga name it. It's what separates your Been Trill and slowbucks Brands from your Stussys and 10 Deeps.. The story's is missing.
But by all means if these brands want to be shallow vessels floating with half thought out designs because theres nothing real to seed them from then fuck it, Produce.. Keeps forums like Hypebeast and Highsnob something to dissect and chat about.
