Overhead light also reflects off the bodice and bleaches makeup.

Wear a little more to offset the effect, usually more blush.

Make sure the makeup base you use matches your natural shade or your head will appear pasted on. When you are inspecting your makeup, look at your neck and whatever body that is exposed to be sure it is the same color and brightness as your face.  Blend well and be sure there are no lines or edges, especially near the jaw line where the makeup ends.

Use a little lip gloss to highlight the lip.  That little reflection can make a portrait sparkle!  If your lips are cracked and dry, condition them for a month before the wedding so they can be their most attractive for your pictures.

Your makeup should not be obvious. Sometimes it takes a lot of makeup to make it appear as if you are not wearing any.

Double check your bridesmaids.  Try to get their makeup to match so you do not have a heavily made up one next to a girl who hates makeup.  See if you can get the noticeably made up bridesmaid to tone it down a little, and can we get a little lipstick and blush on the other?

Stay away from makeup fads, since you want your look to stand the test of time.
