Best Dressed of the Week: Kaley Cuoco, Sofia Vergara and Kim Kardashian West get ready for spring

Welcome, spring! We've been waiting -- and it seems so has Hollywood.

The industry's biggest faces said goodbye to March and hello to warmer weather with some stylish statements: Sofia Vergara wowed in an A-line strapless floral dress by Oscar de la Renta, Kate Mara looked chic as ever in a neon patterned Prada mini-dress, while Kim Kardashian West took center stage in a very tight black Versace gown.

Kaley Cuoco, too, turned heads on the red carpet to support Seth Rogen's Hilarity for Charity. The sheer, black lace gown by J. Mendel hugged the actress in a corset-like fashion, a look which she paired with strappy Stuart Weitzman heels.

Other standouts from this week's most stylish spottings include Allison Williams in a chic plaid pantsuit, Rosie Huntington-Whitely sporting a divine leopard ensemble by Attico and pregnant Duchess Kate's tailored Catherine Walker coat.
