Steal this Hairstyle!

If you want to try it:

Take a section of your front hair. Use less than you would if you were going to do a half ponytail. Backcomb the underside of it just enough to create so serious volume under there.
Side note: if you have thin hair try a volumizing product like Bumble and Bumble's Thickening Spray when it's wet.
Then wrap it in a rubber band and bobby pin it in place so that it's poofed up a bit. Very modern and yet, so retro.
Good luck and thank God for Audrey!!
