N.,
You are just too funny. I never encountered anyone who was worried about other peoples' make-up. Don't focus on this...just focus on the time the ladies get to spend with each other, talking and laughing. Plus, in my experiences, ladies are usually more interested in eating and talking than what their faces look like. :>)
I used to be a Pampered Chef consultant and one of the recipes that has always been a big hit are "Malibu Wraps". They are rolled tortilla sandwiches with a cream cheese and pineapple spread, cucumbers, red peppers, carrots, sprouts (optional), baby spinach leaves, and deli turkey breast meat. I have served them not only at Pampered Chef parties but also at my other women functions and they have always been a huge hit. When you cut them into individual servings, the inside color combination from the different veggies, make them look so attractive. They are SO easy to make. If you want the recipe, contact me offline and I'll send it to you.
Fruit is always great to serve and if you want to be unique, serve fruit kabobs instead of a fruit salad. The last time I made fruit kabobs for a ladies function, they were gone in no time at all. Again, they are so easy to make and have a wonderful display presentation. You can do the same thing with veggies.
If you plan on serving a dessert, make it simple and light. Angel food cake with a strawberry topping would be good.
Hope this helps!
