With natural matte lips like Angelina Jolie's, the hot guy you're crushing on might actually work up the nerve to ask you out!

[edit] Steps

Exfoliate your lips with a warm and wet wash cloth by wiping back and forth gently for no more than 30 seconds. If you do it for longer than 30 seconds, or 30 swipes, it will cause your lips to become rough and unmanagable!
Apply a good lip plumper (the most recent in lip enhancing technology). There are a few good brands sold in department stores and beauty supply stores. They literally plump up, smooth out and moisten the lips. For a natural alternative, cayenne pepper can be used. Apply a very small amount of the powder across the lips, and top with your favorite lip gloss. The cayenne will plump and color the lips by making the blood flow increase (the same action the lip plumpers create), and the gloss will provide shine and moisture.
Line and fill in your lips with a light brown or nude lip liner pencil (match your skin tone as closely as you can).
Apply a matte flesh-toned lipstick.
Blot the lipstick by gently pressing your lips closed with a tissue in-between.

[edit] Tips

Alternatively, some lip glosses(like Lip Venom) use ginger and cinnamon to increase circulation in your lips to create fuller "bee-stung" looking lips. The cost of this beauty might be a slight burning feeling in your lips. However there is danger of an allergic reaction, so don't lick your lips or your throat may swell up which is extremely dangerous.
Reduce shine and make your lipstick last longer by adding an ever-so-thin layer of baby powder with a brush.
If the look is a bit harsh for your taste, try adding some shine with clear gloss.
Make-up artists like this trick, too. Add dimension by taking a liner about 2 shades darker than the lipstick and drawing in a "shadow line" under the middle of the bottom lip. This can be very tricky to master, so make sure you practice before you wear it out. Study pictures of celebrities who have similar lip shapes to your own and try to copy the shadow line found on them.
Try to constantly use a lip gloss that has peppermint, spearmint, or cinnamon in it, preferably Mentha shine from Bath and Body Works.
Using medicated lip balms, such as Carmex is great for keeping your lips soft and beautiful. Also, they're more receptive to treatments, such as plumping and infused lip glosses.
If you have full lips, don't use lip plumper.

Do not get so focused on your lips that you lose sight of how beautiful the rest of your face is.
Nature usually shapes the lips to fit in with the other features on the face. The correct balance is much better than something completely out of proportion.
Also do not forget that this 'bee stung' type look is just a fashion statement. Next year tiny lips, (which are cute) could be all the rage!
If you do want to try the lipstick type so-called plumpers, read the online reviews, particularly the unbiased ones. It seems most of them do not work.
A better attitude, a different style of clothing, or a different hair color might be a lot more important than attempting to mimic Hollywood's current favorite lips.
Be yourself. It is important that you do not get obsessed with getting someone else's features. It is alright to enhance your looks and feel more attractive, but stay true to who you are and do not get obsessed over it.
If a lipstick plumper hurts your lips it most likely has a chemical you are allergic to in it. Go for a higher up brand.
