Always be careful what you tell your wedding participants... it's not like you get a do-over of your wedding day.
Apparently this bride told her bridesmaids they could wear what they wanted to stand up for her on the big day. So her sister/maid of honor took it to the nth degree. She chose to dress in a full-blown T-Rex costume.
Watch sis, and the poor best man that had to walk her down the "aisle," clumsily navigate the awning on the house, and STOMP her way to the altar.
Of course, if I was the DJ at the wedding I'd have to play the song below sometime during the night.
