On opposite coasts, Ke$ha and Solange Knowles each rocked two completely different styles with one common theme in mind: bold.

Solange wore an Olcay Gulsen Silk Double Slit Dress to Emenegildo Zegna's latest men's fragrance launch in NYC. The singer-songwriter looked amazing in the peach dress with lots of leg, simple gold jewelry, and loose, curly hair. Feeling daring? You can even purchase this same dress which is now 50% off the retail price here.

Meanwhile, Ke$ha attended KIIS FM's Jingle Ball at the Nokia Theatre’s L.A. Live in Los Angeles. Celebrating the release of her new album, Warrior, she wore 7 For All Mankind's Black Velvet with Gold Foil Brocade Skinny Jeans and Blazer as she performed her hits like "Your Love Is My Drug" and "Blow."
