Jessie James Decker's complete style transformation

There are a million reasons Jessie James Decker should be on your fashion radar. 

If you've caught her on E!'s reality show "Eric and Jessie: Game On," which the 30-year-old country music singer stars in alongside her NFL husband Eric Decker, then you totally get our fashion envy. The mom-of-three has a killer red carpet style, but her effortless and casual day-to-day looks are even more chic. She's even launched her own line, Kittenish, and partnership with JustFab, making it easy for us to copy her own style.

Plus, she somehow makes being pregnant while wearing glam red carpet gowns and sky-high heels look easy, if that's even possible!

But Decker's style has seen its fair share of ups and downs. Since emerging on the country music scene back in 2010, her style has evolved from fringe, tight mini skirts and punk rock t-shirts to include chic jumpsuits and red carpet-worthy gowns.

Our favorite on the star? The cranberry figure-hugging gown by Nookie she donned at the 2017 Country Music Awards!
