A good eyeliner can be a girl's best friend. By drawing a simple line you can define the shape of your eyes, making them look bigger and clearer. When choosing eyeliner, go for the waterproof variety. Test the durability by drawing a line on the back of your hand and waiting a few minutes before seeing if it rubs off easily. Mac Powerpoint Eye Pencil ($115) It's soft so it's easy to create a smudged effect, but this means it wears off after just one afternoon. Syvania Extra Waterproof Protective Lip and Eye Pencil ($48) A poor quality pencil which doesn't show up very clearly on the skin. You can hardly tell you're wearing it. Shu Uemura Make-Up Pencil ($80) No wonder Shu Uemura is one of the most popular make-up brands. Although this is white, it draws a clear line and is highly waterproof - only special eye make-up remover can take it off. Bobbi Brown Long-Wear Gel Eyeliner ($140) This waterproof liquid gel glides on smoothly and dries in an instant, but you will need to buy a separate brush to apply it. Gig Eyeliner Pencil ($40) The texture is rough, but at this price, you can't complain. It is long lasting and has an intense colour.
