Do a white party theme with white lanterns, table cloths, "milk vases" and a white carnation buttoniere at every place setting. Your daughter could wear a white top hat with white boa feathers and long white opera gloves with any dress for added drama.
Serve a white dessert bar placed on all kinds of white milk dishes/cake plates such as white macaroons, vanilla cupcakes, clear mint candies, rock candy, white jelly beans, white marshmellows, white jordan almonds and other white candy that you could find in your 99 cents store. you could also serve a white drink (non alcohol). If you want to add liquor, add white rum (Bacardi is best).
Coconut Banana Cooler
1 frozen banana
1/2 cup coconut milk
1/2 cup Greek yogurt
1/4 cup skim milk
1 1/2 tablespoons honey
2 teaspoons lime juice
Directions: Peel the frozen banana and cut into small chunks. Blend banana, coconut milk, yogurt, skim milk, honey and lime until smooth. If the drink is too thin, add ice and continue blending. If the drink is too thick, add more skim milk until it is the desired consistency. Pour in a festive glass over ice. Serves 1.
I would add a coordinating color, like silver and on the tables place silver votives and white candles and white potted plants (a little green would not hurt) that you can buy from Home Depot or other plant store. Add white tissue paper and clear wrap and tie with raffia or white cord around plant to hide the plant pot.
You can buy cute white novelties such as napkin holders, sashes for the table, etc.
For food, have a buffet with sushi with white rice, mini grilled cheese with white cheese and bacon, small shot glasses of white cream of turkey soup, a white rice & chicken dish, pasta with alfredo sauce, white popcorn, and a carved meat.
