Practicality matters on a day that can go from early afternoon until the first rays of sunrise, so you might go for something larger than the occasional evening clutch, but definitely smaller than your everyday tote bag. Size is important as you will need quite a few things to go through the night, your bag should be roomy enough to have your phone, lipstick and powder to refresh your makeup, some tissues, as happy tears are guaranteed and even a pair of foldable ballet flats for the dancing floor. Even better if it can be worn on the shoulder and you will be able to help the bride with anything she asks for or just hug your friends freely.
