For Kate's gorgeous strong bone structure, you gotta fake it till you make it. A strong brushstroke with a thick bristled brush should do the trick, with some highlighting just above your 'bones and defined hollows.
For sweet 16 year old Lindsey's fresh face, go for a light, toned down look. The nearly there, dewy look is hot, hot, hot for spring. So make sure you use cool,cool, cool colours.
And last but not least, Gisele. The biggest supermodel of our time, and flawless skin all year round (bar her one bad skin day) A defined cheekbone will do the trick, even if you can't see them. Suck your cheeks in making a fishy face to find the right outline, and get brushing. This is probably the most natural of the three. However, you have to be delicate; too much and you'll end up St Tropez'd in all the wrong places.
Good luck ladies!
