Katy Perry's bright blue hair continues to influence her style in a major way.
The "Part of Me" singer, 27, coordinated her colorful 'do -- which was crimped and pulled into a super-tight, oversized bun -- with a sparkly cut-out, leather-detailed sapphire mini while partying with French male model Baptiste Giabiconi in Paris on Tuesday night.
Perry, who's known for her daring fashion sense, debuted the cobalt coif shortly after her 14-month marriage to Russell Brand ended with his Dec. 30 divorce filing.
"She wanted to go this particular color blue for a few weeks now. Katy is the ideal client because she loves to be creative and unpredictable with her look." the songstress' colorist Rita Hazan told Us Weekly in January.
