Most brides hire a professional photographer to capture every moment of their wedding day. You'll still be pulling out those pictures when you're old and gray, so it's understandable that you'll want members of the wedding party to look their best.
But we draw the line at firing a bridesmaid because she revealed she's pregnant and you don't want her to look "fat" in your photos. Also unacceptable? Sending a waxing salon gift card to your future sister-in-law a few days before the ceremony with a note that reads "upper lip." Tone it down, and try to see others' flaws as reasons you'll look all the more radiant on your special day.
