Can't imagine being without your mascara or lip gloss? Every girl has a cosmetic she can't live without, so be sure to pack it in your beauty bag before you leave the house. Remember: It's essential if it's important to you! If you have a favorite lipstick that you plan to wear on your big day, put it in your cosmetic bag first. Wearing grandma's perfume as you strut down the aisle? Make sure it goes into the bag before anything else. The last thing you want to forget is the one thing that's sure to make you feel beautiful and confident when you say "I do."
