formo is a clothing style that is a combination of emo dress style and formal dress style. an outfit with a suit jacket of any sort with a tie and skinny jeans would be formo, or a nice button up jacket with any type of jeans and skateboarding shoes would also be formo. it is making a statement that you aren't exactly emo - you are a bit more classy.
