The '80s are back in full effect!

Brooklyn Decker went decked out in '80s garb for her husband Andy Roddick's foundation party on April 14.

The Sports Illustrated model sported a bow-adorned dress, ruffled socks and a sky-high side ponytail to the "Bogey Down Dinner," which took place at Barton Creek Country Club in Austin, Texas.

The 26-year-old stunner took to Twitter to show off her over-the-top costume and proclaimed

"The 80s are back y'all" alongside a photo of her themed ensemble and coiffed updo.

Decker danced up a storm at the annual bash alongside close friends and family and played with party favors including retro shades and an oversized cellphone.

The Andy Roddick Foundation supports children's after school activities and has raised over $11 million dollars to fund after school programs and build a state-of-the-art facility in his Texas hometown.
