Shape guest editors Kristin Cavallari of The Hills and Jennifer Garner, a star of Valentine's Day, pick their favorite beauty products.
Cavallari, 20s guest editor, likes L'Oreal Paris Pro Manicure in Honeysuckle. "A sheer nude shade is great for every day. It goes with any outfit," she says.
Garner, 30s guest editor, picked Essie Nail Polish in Mademoiselle. "It's a classic and it doesn't fade the way brights do," she explains.
