Sports Illustrated seems to be celebrating the spectrum of female body types in its 2016 Sports Illustrated Swimsuit issue, which features plus-size model Ashley Graham on the cover.

The issue also features model Hailey Clauson and UFC fighter Ronda Rousey, representing a range of muscular to full figured women. It's the first time in over 50 years the issue features three different body types, according to the Huffington Post.

Graham, 28, took to Instagram to express her happiness with the cover:

"Truly speechless!!! This cover is for every woman who felt like she wasn't beautiful enough because of her size. You can do and achieve anything you put your mind to. Thank you so much to the entire @si_swimsuit team! I'm so excited to be a part of your family. I love you all!!!#siswim #beautybeyondsize"

The magazine explained its selection, saying: “The three covers of Hailey, Ronda and Ashley celebrate the new SI Swimsuit,” said SI assistant managing editor MJ Day. “All three women are beautiful, sexy and strong. Beauty is not cookie cutter. Beauty is not 'one size fits all.' Beauty is all around us and that became especially obvious to me while shooting and editing this year's issue.”

The issues hit newsstands Monday.
