White wedding dresses are so 18th century these days. I was under the impression that only first-timers got that privilege of wearing white. When one of my relatives wore a white, full length, dress complete with veil, to her THIRD wedding, my cousins and I nearly fell over laughing as she walked down the aisle (it was a Catholic Church BTW). Yes, we were sitting in the front pew. Yes, in my opinion, personal style is one thing; trying to convince your wedding guests, and family, that you're a 'first-timer', well that's just a great big gamble right there.
Blue, Lavender, Pink, full length, or better yet, micro-mini length, should be an option. This is the 21st century, and if the bride is a fifth-timer, and she still has great legs, let her wear the micro-mini Blue number with a 20-foot train as she walks down that aisle to say her "I do's".
