Check out this cool GIF made by The Greatist that shows ideal body types and how they've changed over the past 100 years.
Thanks to Kim's famous rear and hits like "Anaconda" and "Booty," big butts are totally in these days! American men seem to agree, too. According to a 2013 study of heterosexual men in the U.S., 59 percent of men prefer butts over boobs.
But if you're not blessed with a Kardashian-esque backside, don't despair. The GIF shows how much beauty standards differ throughout the decades...one year major cleavage may be all the rage, then the waif look is in.
The takeaway? Learn to love what you've got, because confidence is always in style.
