Last night in Los Angeles, actress Drew Barrymore strutted the red carpet in a vintage metallic chain mail frock at Nylon's August issue party to celebrate Express Denim.

And while she is known to wear Lanvin and the like, this dress was a particular standout both in design and affordability. "It was $25 and she bought it at a vintage store in Austin, Texas," her rep told StyleList.

It's not surprising that Barrymore, ever the fashion butterfly, picked up the geometric piece. "I never have time for shopping," the actress told the mag this month. "I like it...I think? If I ever do go shopping, I hit thrift stores..."

Further complimenting her overall ensemble was her ombré hair and simple accessories. Namely, classic gold hoops, a charm necklace, and fab YSL Tribute Too pumps.

The event, hosted in her honor, was also attended by Kelly Osbourne, "Hills" star Stephanie Pratt and 90210 actress Shenae Grimes.
