5Infinity Braid
This one looks very simple, but it is so cute for a summer night out.
Take a small section of hair from the left side and make a circle at the back, take some hair from the right side and secure it in your left hand between middle finger and ring finger. Then put it over your left thumb.
Take the section, which is over the thumb and start to braid. Cross it under section B (on the picture bellow), then over C(the top section), under D and over E and you are done!
Here’s a picture to help you understand the process:
