I made a quick tuto for a simple, yet impressive looking hairstyle. It works even better if your hair's a bit longer than mine.
1. Divide your hair into two sections. Separate a small section of hair on the other side from behind the ear and make a small plait.
2. Plait the rest of the hair as shown. As you can see my plaits are a bit loose but tight plaits work just as well.
3.& 4. Attach all three plaits over or on top of your head (depending on how long the plaits are) with bobby pins. You can try to tuck the ends of the plaits under each other, it makes the whole do look neater.
