Bridesmaid makeup/hair/gift

So I have a specific look color wise (gray/silver eye shadow and light pink/nude lip) I want my bridesmaids to wear for make up. I'm worried about whether or not I should provide it for them, though they all do wear make up, know how to apply it and so on. I'm already giving them floral robes as gifts and most likely paying for their hair to be done, so I can't really afford extra expenses. Should I expect them to be able to provide the correct makeup for themselves? What do I do if they cant?
