When a character wears their clothes with both or one of its sleeves rolled up. This can be either to cool themselves off, to prevent the sleeves from getting dirty or wet, because of clothing regulations (for example uniforms), or because of their taste in fashion.
If the sleeves are visibly only folded up once, use sleeves rolled up. Not to be confused with sleeves pushed up, in which case the sleeves are only pushed up the arm, instead of being folded up.
