I didn't notice it until my brother introduced me to a bunch of his mates and they literally look the same. My brother's in his mid to late 20's and it's like this weird fashion choice mixed with weird slang, "mush" instead of "mate", "minging", "safe", day to day attire of him and his friends group is always some sports branded baseball cap, usually Nike and grey or black, gold chain necklaces, matching tracksuit (again usually Nike, black or grey) and expensive Nike Air Max trainers that cost like 120 quid. They all listen to the same music and I saw my brother watching videos which had similar groups of people doing stuff. Is this some new trend I didn't notice until now? Can't keep up nowadays
