The beauty of a liberal arts degree is that you can go into whichever field you want. If you take a look at http://www.wesleyan.edu/careercenter/career-outcomes.html you’ll see that there is a pretty even spread. You could easily position yourself for business + fashion with an econ/psych double or even just one of those. And if you decide business or fashion isn’t for you, there are plenty of other fields you can enter, or get an MBA. Most people at Wes major in something they are passionate about, and then get into the field they’re interested in, regardless of how directly related their major was. Yes, most at Wes get a graduate degree, but you really can major in anything and you haven’t eliminated any fields going forward. There are plenty of religion majors going to med school and plenty of sociology or history majors getting MBAs.
I think the bigger question is whether you want a small suburban school or a large urban one. There are numerous transfers from NYU to Wesleyan every year who decided the lack of a traditional campus wasn’t for them (and I imagine a few going the other way as well who wanted the Big Apple in their backyard).
