Felicity Jones' TIFF 2014 Dress Brings Elegant Glamour To Toronto

Felicity Jones is quickly becoming our top choice for best-dressed at TIFF 2014 thanks to her impeccable style.

The "Like Crazy" actress—who attended the Hollywood Foreign Press Association & InStyle party Saturday night in a breathtaking Armani Prive frock—upped the ante on the Toronto Film Festival red carpet Sunday evening.

Wearing a form-fitting cocktail dress with a black stripe hugging her waist and a jaw-dropping open back detail, the 30-year-old Brit was the picture of elegance and glamour at the premiere of her upcoming film, "The Theory of Everything."

Felicity was joined by her co-star and fellow Brit, Eddie Redmayne, who displayed his usual flair for style in a daring green suit.

Those Brits really do know how to rock a red carpet.
