With her older sister, Beyonce, stunning in designer Nicolas Jebran, Solange went budget with H&M Studio Collection tuxedo jacket, $79.95, and pants, $69.95. The "Losing You" singer, 28, wore the loose-fitted look without a shirt for added sex appeal and kept her hair and makeup natural, save for red-tipped eyelashes.
Sparks, 24, also chose a wallet-friendly frock with the Simply Intricate FM Dress. The plunging neckline and front-slit style, which retails for $168, showed major skin while the fitted waist showed off Jason Derulo's love's curves.
Singer Mary Lambert also redefined red carpet style in a look that cost less than most celebs' shoes. The "Same Love" collaborator, 25, wore a fit-and-flare dress with a red belt at the waist. The Wild Floral Dress by City Chic retails for $138 but is on sale now for just $103.50. "I love floral," she told Us Weekly on the red carpet. "I like pretty things and this is pretty."
