Love it or hate it, Gwen Stefani is always pushing the envelope when it comes to fashion.

The 46-year-old singer attended pal Shelli Azoff's star-studded birthday party on Friday in Los Angeles, and definitely turned heads in an edgy black dress featuring panels held together by black vertical ribbons. Stefani paired the unconventional frock with fishnet tights and black-and-gold stiletto Azzedine Alaïa boots.
