Getting nerdy and technical I know, but Fubu, Cross Colours, Rocawear are considered 'urban wear or even Hip Hop wear' by most....not 'street wear' by definition, FYI.
Those brands are absolutely different than
these brands...which encompass what street wear really is (by definition/what we used to know it as).
But I get what you're saying and OF COURSE....those brands you mentioned were literally worn in the streets.
As discussed, the term street wear has become skewed over the years, but surprisingly Wiki has a decent definition below. The difference is the FUBU's, Cross Colours, Rocawears were straight up Hip Hop and didn't incorporate skate, surf, etc...
Streetwear is a style of casual clothing which became global in the 1990s.[1] It grew from New York hip hop fashion and Californian surf culture to encompass elements of sportswear, punk, skateboarding, 1980s nostalgia, and Japanese street fashion. Later, haute couture became an influence, and was in turn influenced by streetwear.[2] Streetwear centers on comfortable clothing and accessories such as jeans, T-shirts, baseball caps, and sneakers. Brands may create exclusivity through artificial scarcity; enthusiasts follow particular brands and try to obtain limited edition releases, including via proxy purchases
