I use Bath and Body Works. Have always had good luck with it. Have read good stuff about Jergens as well, but not tried.
I recommend you start now, so you give yourself time to get good at it. How much to apply, how much to rub in, etc. Keep in mind most have a bronzer in them that washes off the first time, but you still have the color.
I've put on white jeans, shorts, etc. after I have dried, but the bronzer rubs off onto my clothes. Washes out...but think about that and your cream dress. Especially if you plan to dance up a storm...and sweat.
