The Groom and Bride. The Groom wanted to rent a tux in Vegas, but found instead a completely purple outfit that cost him the same to buy then to rent. So he went with it. The Bride found a dress in D.C. a mere few days before Vegas and borrowed a friend's hat for the picture.
For some reason, and completely unplanned, the rest of the girls all dressed up by different sequential decades:
Rest of the Gang. Antine as a Cowgirl in the 1930s, 007 in cocktail wear in the 1940s, Yanna as a 1950s Housewife, Mala sporting a fro' in the 60s, Sema with a grooving dress reminiscent of the 1970s, and Nancy with block print from the 80s.
(Note: they got married at the very classy Graceland Chapel so yes, that is astroturf on the ground.)
