I've heard of a bad hair DAY, but Barbie's had multiple bad hair YEARS...
1991 Barbie reminds me of my sister during the 80's, except Barbie's hair wasn't nearly as big.
1998 Barbie looks like she thinks she's better than you.
2006-2008 Barbie looks like she has absolutely nothing going on upstairs.  The lights are on, but no one's home.
2015 Barbie says, "After all these years, I finally look cute and friendly again!"
