'heroin chic') which basically means, in some eyes, the ideal '90s butt was super tiny and kind of flat. Back then, supermodels like Kate Moss and Elle Macpherson popularized the 'waif' look, (a.k.a. Supermodel butts (whether they were small and flat, small and round, or big-ish and round) were the ideal booty type in the 1990s. Just to prove the futility of it all, here are 11 examples of how America's 'ideal' butt has changed over the years.

All butts are good butts, and the 'ideal' butt has changed so much over the years, that stressing about it is pointless. How can women and girls not feel dissatisfied with the shape of their backsides (or any other part of them for that matter) when the 'ideal' female body type is ever-changing, predominantly centered on white women, and consistently unattainable for most women? It's madness. When Nicki Minaj released her bootylicious cover of Anaconda last year, the public was outraged - but when Victoria Secret angels sport thongs on the runway or on the cover of Sports Illustrated, they're basically revered as goddesses in human form. Before Beverly Johnson graced the cover of Voguein 1974, a woman of color had never been featured on the magazine's cover - and that was barely 40 years ago. If you're skinny, society says you're not a 'real' woman because 'real women have curves.' On top of our culture's obsession with the size and shape of women, our beauty standards have also been consistently whitewashed.

If you're plus-size, society tells you to be thinner.

But the whole concept of the 'ideal' butt (or the ideal body) is what leads women and girls to wish for different body types in the first place. Actually, it's kind of awesome that big butts are having a moment - because they're beautiful.

Of course, this isn't necessarily a bad thing. You've heard the saying: 'Girls always want the body type they don't have.' Today, this phrase could easily be changed to, 'girls always want the booty type they don't have.' With the rise of Kim Kardashian and Nicki Minaj, the 'ideal' butt has definitely changed over the past decade.
