These fun thongs are not only for the Bride and Groom. Consider providing a pair for each of your attendants to wear while they enjoy a day at the spa, the beach or even at the reception. These also would make fabulous guest favours for weddings with a beach or tropical theme. To determine the appropriate thong size, measure your foot from toe to heel. Select the thongs that are the same or slightly larger. These are flip flops and do not require an exact fit.
