Felicity Jones's Oscar 2015 Dress Looks Like It's From Prom

Felicity Jones has rocked her way through award season red carpets this year in tons of stunning Dior Haute Couture gowns so we were surprised when she ditched the French label for an English brand at the Oscars.

On Sunday, "The Theory of Everything" star hit up the Oscars 2015 red carpet wearing a massive silver Sarah Burton for Alexander McQueen gown that definitely channeled her inner prom queen.

And can we talk about that high neck with the pearl embellishments? Fab! The English beauty styled her huge gown with simple makeup and a pretty updo with her signature bangs

What do you think of Felicity's dress?
