The halter-neck style of the dress allowed for a flash of skin at the sides.
This combined with a super low-cut back added sex appeal to the otherwise demure gown.
Due to the intricate detail at the front of the frock, Biel opted to keep her hair and make-up simple.
The brunette beauty swept her locks into a cute up-do with a quiff, adding a playful dimension to the look.
Biel needs little make-up to look gorgeous and kept eyeliner to a minimum, whilst emphasising her mouth with a slick of pink lipstick.
Ruffles can be a great way to spice up a plainer outfit, such as a little black dress.
If you're busty, steer clear from ruffles around the chest like Biel's, as they could make you appear top-heavy.
If you're petite, try detail around the waist to give the illusion of a curvier shape.
Biel's co-stars Toni Collette and Dame Helen Mirren also joined her on the red carpet, with Collette looking gorgeous in a fitted red dress.
Dame Helen opted for a lacy black and gold number, teamed with stunning chandelier earrings.
Sir Anthony Hopkins, who plays Alfred Hitchcock in the biopic, was unable to attend due to work commitments.
