Jessica Alba Does a Perfect 'Romy & Michelle' Halloween Costume!

Jessica Alba and her best friend Kelly Sawyer dress up as the title characters from Romy and Michelle’s High School Reunion for their 2015 Halloween costumes on Friday night (October 30) in Los Angeles.

The ladies attended the Casamigos Halloween Party with their husbands Cash Warren and Jamie Patricof, who dressed up as Top Gun characters. The event was hosted by real estate developer Mike Meldman and fashion guru Rachel Zalis.

“#romyandmichelle #halloween @kellysawyer n I invented post-its,” Jessica captioned the photo on Instagram.

Earlier in the day, Jessica dressed up as the Evil Queen at her office’s costume party. Her daughter Haven went as Cinderella!
