Our definition of what is cool and beautiful changes by the minute. In the early '90s, I wore nothing but flannel shirts and then promptly threw them away in the early 2000s. Now I wish I had those same shirts because everyone is wearing flannel again. 

A new time lapse video from Cut.com shows us just how dramatically different our definitions of beauty have changed over the years. The video shows a model starting at 1910 style and takes us all the way up to 2010, with stops along the way every ten years.

It's pretty remarkable to see the dramatic shifts in hair, makeup, and style by decade. And it definitely makes you realize that we have no idea what the future beauty trends may hold.
