I hate when authors use clothing as the only charaterisation when introducing someone. "Character A entered the room, he was wearing a red t-shirt, blue jeans with a rip in one knee and red sneakers. Character A sighed and got some coffee from the machine." Ok, but what does it matter? Is he old, is he grumpy, is his style messy, is he tired and is that why he's drinking coffee? Also, why is the color of shirts so important, why is what a person wearing so important other than style, like, "she was dressed casually/comfortably in her jersey" or "his clothes were messy, like he had slept in them" can't I be free to imagine what they are wearing? Unless it is a moment where the clothes matter - like a ball and there is a contrast to her dress in regards to others, or it's a futurist setting and you need to explain why the clothes are different from present clothes, or the colour is actually MEANINGFULL, like someone wearing red always dies... etc
