Jessica Alba and Jessica Chastain both showcased wedding-worthy gowns on the red carpet this week. The question is, which Jess are you?

Jessica Chastain
No one does old school Hollywood glamour like Jessica Chastain, and she was out to prove just why at the Governors Awards. Bride’s hoping to channel simple elegance would be wise to take the lead from the star's plunging ivory gown, which featured a sheer lace panel at the neckline and an open back. The most standout detail of the floaty number? That soft, waterfall hem – note how it shows off those strappy shoes at the front, but cascades into a mini train at the back.

Jessica Alba
The strapless princess gown is a classic bridal style, but here Jessica Alba updates the look with a metallic bodice featuring an intricate embroidery detail. The A-lister showed off her look at the Baby2Baby charity gala this weekend and, like Chastain, chose to complement her look with soft, wavy hair. Jessica's dress is actually a separate bodice and layered white skirt from Andrew Gn's Spring/Summer 2014 collection. Proof that separates can also be a winning big day look.
