You only need two things to create this look:
A few bobby pins (i like to use gold tone bobby pins so that they blend in with my hair color).
Clear elastics (purchased at Sephora).
Begin by creating a loose side pony tail.
Here are a few pictures with my little fur son Jack. He wanted in on the action so today we'll call him Fashion Maven JACK!
From here, begin to twist the hair around the pony tail to form the bun making sure that this is happening on one side only.
Add a couple of bobby pins as needed to secure the bun.
And VOILA! Easy as pie... try it!
