What clothes would you want to wear if you'ld cross dress for a day?

Inspired by a question earlier today, and my answer to it, i thought about this:
If you would (want to) change into the clothes of the opposite sex, what kind of clothes would that have to be for you?
If you are not even close to considering such a thing, use your imagination, if you please.
I realize that i would not look quite like a woman, but if i did it one day, it has to be a women’s suit with flat shoes (i’m already 6 feet 5).
So, ladies, what men’s wear for you?
Men, what dress for you?
It is merely for fun, this question, so don’t be shy!
