Who wears short shorts!

Jessica Simpson, 35, looked flawless while on vacation in Mexico on March 30, 2016.

The fashion designer looked casual and cute in a purple and pink bikini top, a crocheted white cover-up top, a cowboy hat and purple sunnies. She also opted for a pair of distressed denim shorts, proving she can still rock her Daisy Dukes like nobody's business. Of course, the short shorts are very reminiscent of the pair Jessica Simpson rocked while starring in the 2005 "Dukes of Hazzard."

The mom of two -- Maxwell Drew, 3, and Ace, 2, -- has worked hard to get her pre-body weight after two pregnancies in a row. In 2014, she paired up with Weight Watchers again to hit her goal weight and it shows! Jessica Simpson not only has has abs that are envy-worthy, but she has toned legs for days -- which is perfect since Jessica loves to wear shorts.

Jessica Simpson is in Mexico for her BFF stylist Nicole Chavez's birthday. Also along for the fun weekend adventure is CaCee Cobb, and from the looks of their Instagram it's been a pretty fun week so far, starting with their private plane adventure.
