I would say that adding "designer, and entrepreneur" is a pretty significant improvement on a resume relative to "model". Again, this roughly parallel people that refer to Obama's pre-Presidency career as being a community organizer. OK, that's true. He was also a lawyer and Senator, which seems relevant.
I'm personally more likely to be impressed with Ms. Obama's resume because I tend towards being more impressed by academic achievement, but my understanding is that modeling and fashion are viciously competitive, cut-throat industries.
