Fashion was different in those days. It's a dated look now for the youth, but some of those patterns and fabrics will always be money if put together well. When punk came into the picture and it became fashionable to wear distressed clothing, the writing was on the wall. Hip-hop in its early years was still keeping it fresh and in tune with with the aesthetics of the pictures you posted, but somewhere down the line it became fashionable to wear distressed clothing for Black people. Somewhere when rappers wanted to be rock stars the aesthetics followed, this was after the shiny suit, and streetwear/BAPE era of the late 90s and early 00s. Tastes in fashion change, but affordability is also an issue. Quality clothing now costs more when you only factor in inflation over the years. Combine that with marketing and corporations trying to multiply their profits and you get a clearer picture. Then you gotta check back with history, once the States switched from a manufacturing economy to a service economy the wealth of all classes were affected. Focusing on the middle class does not get the full picture either. Lower classes were affected due to losing access to some jobs that could have allowed them to dress like the other people in OP. Everyone is affected by the economic changes in the country, and fashion changes. The rise of fast fashion in the 2010s is a reflection of these changes.
