Jennifer Garner's complete style transformation

Jennifer Garner is a total red carpet queen!

Even during her "Alias" days, Jennifer ruled the red carpet. From breathtaking couture gowns to the occasional jeans and a T-shirt outfit, the star has always dressed to impress on the red carpet.

Her most memorable looks?

At the 2016 Oscars, the actress stunned in an off-the-shoulder Atelier Versace gown that showed off her flawless figure. At the 2007 Met Gala wore Valentino-signature red -- a strapless dress with a dramatic train -- that completely stole the show.

And how could we forget about her 2018 Oscars ensemble? Jennifer shut down the red carpet in a blue Versace number. She kept all the attention on the breathtaking blue number, opting for a wavy hairstyle and simple makeup.
