Well it depends on where you decide to attend fashion college. I have friends who graduated from FIDM/Fashion Institute of Design & Merchandising in LA and they told me that FIDM has a two year A.A. program for fashion designing and if you want to continue your education, you can enroll in their bachelor of science in business management program which I think is great. The Bachelor program can give you the business background of the fashion industry and will help you even more in succeeding after graduating. If you want more information on FIDM's fashion design or bachelor's program, check out their website.

l really don't think you need any schooling to become a fashion designer, You can design and make clothes without going to school for it, but schooling in that feild can be helpful in creating the garments.
A popstar doesn't need as much schooling as the average person because they do not have to go to collage.
They generally need more than 6 years of schooling
Any one of any age can be a fashion designer. However just because you designed a fashion does not mean anyone will wear it or pay for it. For that you need to become a great fashion designer. For that you will need practice, probably some schooling in fashion. and a lot of luck.
