Red Lipstick is hard to pull off, as it can look tacky and cheap if worn the wrong way. Here are some great tips on how to pull it off and wear it with class and style while still looking glamouros and sexy.
1. Condition your lips: Having soft, well conditioned lips is a must when wearing red lipstick. You can achive this using your favorite lip balm. Personally I recommend Eos Organic Lip Balm Smooth Sphere (Summer Fruit), which you can buy online.

2. Line your lips: Use your favorite red lip liner to outline your lips carefully. Once you've done that fill in the rest of your lips to achieve flawless colour. I recommend MAC's Creamstick liner, its creamy texture is softer and will last longer. You can find it in all MAC shops, major department stores and online. Remember to use a shade close to your lipstick's.

3. Colour in your lips: Use a lip brush for precise application. For the lipstick I recommend Clinique's High Impact Lip Colour SPF15 in Red-Y to Wear or Sider Spice. Go for Cider Berry for a more subtle look. I recommend these because the colour is indeed high impact and they have SPF15, which will protect your lips from the sun.

4. Keep the eyes subtle: Line your waterline using your favorite black or dark brown eyeliner. Apply two or three coats of your favorite mascara. Personally, I recommend black, it's much more effective and elegant. For the liner try Magic Khôl from Givenchy in Black, Givenchy is more expensive than other make up brands, but this liner is definitely the best I have ever worn and is worth the extra money.

As for the mascara, Lancome has a great line. My favorite is Definicils Pro in Deep Black.
5. This is optional, but you might want to use a peachy blush to compliment this look, or a highlighter underneath your brow. This will intensify the eyes whilst keeping them subtle.
Good Luck!
