You could get them in your colors-pink, black, orange. Dancing the night away at the wedding - outdoor wedding = flip flops are a necessity! What an awesome idea. Go the cheap route and get Dollar Store flipflops
Here's an idea: use bails of hay instead of renting chairs for a casual, country themed wedding outside . Or any outside gathering! After the party see if you can donate the hay to a farm animal rescue! I like this hay bale seating idea.
