FASHION INSTITUTE OF TECHNOLOGY!
My son says that although many of his friends are the smartest kids in the school, he is not - he is a notch below them. But he got into a top school, because of solid academic performance in the most rigorous classes, and very high achievement in his extracurricular focus (music). He has a decent social IQ, and is just a very nice young man - everyone likes him. So this is not just a girl thing. His comparison of himself to others in his grade is realistic. At the same time, he understood that his very high extracurricular achievement might vault him into a top school - and it did.
When people are not sure what they want to study, I recommend that they go to big schools, with tons of majors. That way, they’ll have many choices. It is definitely possible to make a big school feel smaller, by going to office hours, and reaching out to teachers. Years ago there was an excellent article in the NYT on the theme of “What I Wish I’d Known in College”. The biggest point was to take advantage of office hours to get to know the professors.
Your daughter is in-state for Texas. As such, she should take a very close look not only at UT Austin, but the other top UT’s. One of them might be the perfect match for her both financially and academically. As for getting accepted into a major, at most schools it is possible to move into any major, as long as one does it early, with very high achievement in the intro level classes that are open to all.
Considering “match” schools that are big, have lots of majors available, and are in vibrant cities. Northeastern and Boston University in Boston, Tufts as a reach. George Washington and American in DC (but Georgetown is a possible reach for her, too). Drexel in Philadelphia has gotten much bigger - it’s not just for engineers anymore - and it’s on a campus that has essentially grown right up to Penn’s campus. Penn of course would be a high reach for her. Barnard and NYU are both good reaches in NYC. Fordham would probably be a safety, but not in a great area. If she’s willing to look at flagship state U’s out of state, U Md is a good big school, a commuter train ride from DC. U Mich has everything and the college town feel (although Ann Arbor has gotten bigger than that).
And with her strong interest in fashion and business, what about Fashion Institute of Technology in NYC? Honestly, with how into her fashion-related business she’s gotten, I think she’s sure to get in. It would be a safety for her, yet in NYC, in the heart of the fashion world, and it’s a bargain, even out of state.
