Fashion merchandising. Honestly, you being a guy may be a plus because there aren't many guys out there interested in this sort of thing. Either that or start your own project by posting blogs, pictures, and whatnot on social media and you can advertise your style to gain popularity. You can give retail a try too. You'll gain some experience directly with customers, and plus that's always a good way to get discounts on clothes. If you like it and do well then you can obviously move up the ladder.

You can be a buyer or if you don't think the commitment is too much, you could learn to design clothing and get a job doing that.
