This video is a tutorial by Sunnie Brook describing how to do her version of a ballerina bun, which is really fun and really easy. I've been doing this for a couple months now and even with my relatively short hair, I can tie it into two knots. I really like this style because it's simple, pretty, fast and let's face it, there's something strangely appealing in the thought of tying your hair in knots. Here are a couple photos from about two days ago when I did this to my hair last (and I got tons of compliments all day, so it's a sophisticated style you can trust!). My hair goes in two knots but it looked just fine when I could only knot it once.
