What are the most prestigious fashion design schools in the world?

*I live in the USA, but I wouldn't mind going to another country. I want to go to another country even. However I probably want to come back, and I don't know how my degree will stand then*

Parsons (NY and Paris)
Central Saint Martins (London)
F.I.T (NY)

Most of these schools you need an amazing portfolio.

Also from what I heard Saint Martins takes like 30 applicants a year or something for the Fashion Design course

Thanks
