My favorite would be red. I love red color on so many things tho! Lipstick, cars, flowers,tie, wine!!!
However, any color has this chance to look nice and suit and play a significant role on woman's appearance. But the fact is, choosing the lipstick on it's own due favorite is not enough, for choosing a lipstick factors such as: The shape of the face, the color of the skin, the shape of the lips, the build up and foundation of the make up, and the type of dress and sometimes jewelry and accessories must be regarded.
The second line is my type of favorites.
