Cobalt blue is one of the hottest shades for summer 2012, so naturally Blake Lively (Serena) has already been photographed wearing it as she films scenes for Gossip Girl Season 6 — and looking absolutely fantastic. (What else is new?)

Earlier in July, the GG star donned this sexy, summery Marc by Marc Jacobs silk dress as she filmed scenes with co-star Chace Crawford (Nate) in NYC. She accessorized the look with a printed white Fendi shoulder bag, bright pink Christian Dior sandals, and colorful pink-and-green earrings.

However, Blake isn’t the only one who can pull off this colorful and fun look. Jessica Szohr (Vanessa) wore a sexy cobalt minidress to a fashion show back in September 2011. The former Gossip Girl star chose a figure-hugging Herve Leger design, which she paired with Christian Louboutin pumps.

Both ladies look stunning in their bright blue attire, but we want to know which gal you think pulls of this trend the best! Sound off by clicking the buttons at the bottom of the screen.
