Rainy day wedding forecasted? don't panic, i got you Girl.
1. Buy or rent an umbrella that coordinates with your color palette or opt for clear bubble umbrellas. Pick one per couple if you're buying/renting for the entire bridal party.
2. Many venues and private estates, museums, botanical gardens, etc. allow an hourly rental of their property for a minimal fee if you want a solid plan B.
3. Just have fun with it! Jump in puddles, stand in the rain and kiss!!
4. Schedule a make-up/hair touch-up with your stylist after photos just in case your locks have fallen or mascara has run.
