This week was all about whimsical gowns and sexy LBDs. And the winners are...

Halle Berry in Elie Saab at the 13th Annual Costumer Designers Guild Awards. It's a rare occasion that one gets to see Halle wearing anything other than black, so it was especially refreshing seeing her radiate in this raspberry-red, lace-covered gown.

Elizabeth Banks in Versace at Tom Ford’s Beverly Hills Flagship Store Opening. The actress oozed sex appeal in this belted, cutout LBD, which she spruced up with a pair of colorful Miu Miu sandals. 

Kristin Davis in Oscar de la Renta at the 13th Annual Costumer Designers Guild Awards. The actress looked quintessentially "Charlotte" in this girly, silk-tulle gown covered in black polka-dots and cinched at the waist with a satin bow.

Diane Kruger in Vionnet at the 61st Berlin International Film Festival. The actress looked like a Grecian goddess in this romantic, cream-colored halter gown that featured beautiful pleating, rustic chain detailing and a sexy open back. It's my favorite of the five.

Jennifer Aniston in Nina Ricci at the "Just Go With It" premiere in Berlin. While I would've liked to have seen Jennifer incorporate some color into this completely-black look, I couldn't help but get caught up in this flirty, frilly LBD, which boasted a tulle rosette on the one shoulder.
