The Proposal
Disaster Scenario: You lose or damage your ring.
Are you sometimes scatterbrained? Afraid you might lose or destroy your ring before the big day? Consider buying a strong chain or necklace so you can wear it around your neck when you’re most active. (Trust us, one bride-to-be we know recently damaged her engagement ring during an evening of mechanical bull-riding!) Or, opt for insurance. Most homeowners insurance policies allow for a jewelry rider that covers valuables like your engagement ring. The yearly cost is usually $1 or $2 for every $100 it's worth. If none of those options is your cup of tea, consider having a copy of your ring made by your jeweler for daily wear. Then, you can just wear the real one for special occasion.
The Ceremony
Disaster Scenario: It’s raining on your wedding day.
Even in your most demanding bridezilla moment, you can’t fight the weather -- but you can plan ahead. If you have your heart set on an outdoor venue, rent a tent or ask about additional space indoors. It may cost you extra, you won’t be stressed when you’re finally ready to say “I do.”
Disaster Scenario: You wake up with a pimple.
Do not pick your face! If you have acne-prone skin, speak to your dermatologist about his or her availability on your wedding day (some dermatologists have weekend hours). Most likely, a shot of saline or cortisone will clear up your breakout. If your doctor is unavailable, try a cold compress to bring down the swelling and keep a bottle of Visine handy. This super-secret modeling trick will reduce the redness and minimize minor acne breakouts.
Disaster Scenario: You cry during the ceremony and ruin your makeup.
Nobody said the price of beauty is cheap, so if you have the funds, consider having your makeup artist on standby until the reception for a quick touch-up. If that’s not in your budget, you can always request waterproof and smudge-resistant cosmetics or shoot most of your pictures before the ceremony to ensure that you look your best.
