I'm a little behind schedule on my alt.sewing reading :-) Thanks for posting the pattern picture, Larisa. How lovely that dress will be. Now I understand about the accent waist ribbon, too. Did y'all already talk about her accessories?
Regarding wedding cakes, I had a friend make ours for an afternoon wedding in July. It was cake pans filled with fruit-flavored mousses, iced on the outside, and stacked on pillars like a regular cake. She assembled it moments before the cake cutting because it would all have melted. (108 degrees in the shade.) You can see in pictures it's a leaning tower of mousses! Nobody cared but my mother...
