If you can, eyelash extensions are a good idea, so you're not worrying about anything. You can also always go the falsies route. If you decide to go with regular mascara, remember to curl your lashes, then apply a good tubing mascara that won't flake or smudge.

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!
