| Changing your shoes is fine.
I suggest dark dress pants (every woman should own a pair of black dress pants), with inconspicuous black shoes that don't scream "let's party." Wear either black socks that go fairly high up your leg (so that you won't have a ring of skin showing when you sit down) or knee-high hosiery.
Many young women of your generation are not accustomed to wearing skirts. They have a tendency not to sit properly when wearing them, which is a really bad idea if it's a relatively short, straight skirt. Do not wear such a skirt unless you are confident that you have developed the habits necessary to sit properly. A longer, looser skirt is easier to deal with but also gives a more casual impression.
On the top half of your body, if you wear the oft-mentioned button-down shirt, tuck it in. This means that if your pants have belt loops, you must wear a belt. The alternative is a sweater that your grandmother would approve of (not so short that your middle hangs out, not so tight that an observer could sketch the exact shape of your bra, not so low that you would be embarrassed if the interviewer was standing and you were sitting). If you happen to own a sweater set, that would work nicely. A turtleneck is OK unless you happen to be on the well-built side, in which case it may conspicuously scream "Hey, look at these breasts." Use your own judgment on that one. |
