What are the requirements for you to be a fashion designer?

Well, that can be a lot of things, depending on where you are. Each fashion design school has it's specific requirements, without which students cannot join the school's programs.

Mostly though, good grades in fashion related subjects like art, painting and business are all you might need. Still, some Universities such as the Santa Fe University allows US students to be able to study Fashion Design at the industry recognized NABA (Milan,Italy) by just enrolling at the US school and spending the first year in Italy as a foundation year study.
