Keep it simple here, but remember, the brows can really frame the eyes, so simple doesn't mean forgotten. Shape them a couple of days before the wedding so there's no lingering redness. Then, lightly fill in any gaps with a good brow pencil, and set them with a brow gel.
The last thing we do is the lip. You probably want to be understated here, so don't go too shimmery. A buildable tinted balm is going to work well — you'll be able to easily reapply and they're tough to mess up.
Now, all that's left to do is have fun and enjoy your (friend's) big day!
