When writing a scene, should I really describe the clothes of each character? What is the best way to not mess it?

So —- if describing your character’s clothes helps move the story forward, then you describe them. If describing their clothing enhances the story by telling the reader something about the characters, which is logical since what people wear says something about who and what they are and what their immediate plans are (since people dress for the occasion), then describe their clothes.

But in both cases, think of the story itself when describing what they are wearing and only describe enough to get the point across to the the reader and use words that go with the kind of story you are writing. Colorful words if the story is a colorful one or if the characters are colorful characters. Drab words for characters in a depressing situation. And so on.
