I finally finished writing a bunch of changes to my character's physical appearance and I'm finally getting around to going into great detail about what my character looks like so I wanna know what exactly I should describe. I know about hair colour and height. My character will mainly look the same throughout story so should I describe hairstyle? What the main clothes she wears looks like? Anything I might have missed that would allow readers to get a better idea of what they look like?
I suggest only a general description, for example, if your character is human or human-like there is no need to tell the reader how many arms does the MC has unless he lost one. You can describe a character with broad strokes and still be accurate if you only include the little details that matter, you don't have to be precise like "she was 1,60 meters tall", I bet most people will imagine a normal height unless you describe said character as very short or very tall.
I personally described my characters through different chapters, to avoid a several-paragraph long detailed description. I just told my MC was a short teenage girl with long leather robes and a petite frame in the prologue, then added the blue eyes like her father and long green hair in the first chapter, later added that she dons her hair in a long braid in the second, what kind of boots she wears in the third and so on, you don't have to describe EVERYTHING in a single chapter, let alone a single paragraph.
The reason people dislike that kind of detailed description is due to its association with Mary Sues, even if your character is NOT one, people think it is just because of the way the author describes them, especially if you take your sweet time to describe clothing, avoid describing clothing unless it also serves a purpose, like "she hides a knife in her long leather boots", or if its armor. If it's only a fashionable item, just leave it.
