Wellesley prides itself on being diverse (take a look at the admissions literature, if you don't believe me). How diverse is it really? Probably somewhat above average, but I don't know how much. I have a lot of Asian friends (Wellesley is something like 25{4a082faed443b016e84c6ea63012b481c58f64867aa2dc62fff66e22ad7dff6c} Asian), and I know a bunch of international students. Religiously, it's a little less diverse -- I'm Jewish, and I don't know too many other Jewish students. (Well, I know OF several, but most of them are really religious -- like, I don't know of any other Reform Jews.) That said, Wellesley is really open and welcoming about religious diversity, even if there isn't that much of it. I'm always explaining Jewish holidays to my friends, and they think it's cool. We even tried to make latkes! (It didn't work so well, but we had about two ingredients, so that's to be expected.) LGBT-wise, Wellesley is great. I don't know the statistics, but they are a small but active, open, and welcoming group of. I know several members of Spectrum, the LGBTQQA organization, and they're fantastic. Socio-economically, Wellesley has a pretty decent (and recently improved!) financial aid program, so we have a fair bit of that. And people are pretty open about whether they're on financial aid (I mean, you wouldn't ask, but no one would feel uncomfortable saying they were), so there's not too much tension surrounding that.
The only people who would feel out of place at Wellesley are women who are really set on having your basic, traditional, all-American college experience. We're a women's college, yeah. It's a little different here. You have to come in with the mindset that your experience is going to be a little different -- NOT worse, but definitely different. Also, people who aren't interested in working hard. This is not a school for smart people who don't want to work. Being smart got you in, but spending a lot of time studying is going to keep you afloat. One other thing -- Wellesley women are very PC, and the joke around here is "I'm offended," because people do get offended when you aren't PC. So basically, you have to be open and considerate and, yeah, PC. Other than that, pretty much any sort of person would fit in here. If you know what you're getting into, and you're willing to work hard to get the most out of it, Wellesley will be a fantastic experience for you.
What do most students wear to class? Oh, how it varies. There are some who have the "there are no guys to dress up for" mentality, and so they come to class in sweats. Then there are some who get dressed up and come to class in a skirt and sweater set and heels. Most people are in between. Jeans and a sweater/sweatshirt/t-shirt/whatever is very common. Umm... a lot of people around here have Uggs, but that's the only specific thing I can think of.
Yes, different types of students interact. About half of my friends are of a different race than me, almost all of them have a different religion, a few are bisexual/lesbians, and while I don't know their specific socioeconomic situations, I'm sure there's a lot of diversity there as well.
Where are most of us from? Northeast or California.
Politically aware? YES. Especially with the upcoming election, most students at Wellesley know what's going on, and have an opinion on it. And of course it doesn't hurt that the first viable female presidential candidate is a Wellesley alumna! (Which does NOT AT ALL mean that Wellesley students who support Hillary do so only because she's an alumna, but I think the fact does get people interested in the race in general.) I know a ton of people who are incredibly, passionately politically involved. And yeah, like most private liberal arts schools, we lean left. But that doesn't mean there are no conservatives on campus. A girl down the hall from me is on the executive board of the College Republicans, and they have a hilarious fundraiser going on right now: t-shirts that say "Hillary Rodham for President... of Wellesley College Republicans" (because of course Hillary was a Republican until her junior year at dear Swelles).
Some students talk about how much they'll earn one day, but it's not a predominant theme. Lots of people talk about the future, but not in terms of money. Wellesley women want to go places, do fantastic things, change the world, etc, and yeah, it would be nice to make a lot of money somewhere in there, but I don't think it's what most of us are focusing on.
