When Jennifer Garner [1] hit the Oscars red carpet [2] on Sunday night, I can only assume the jaws of everyone around her immediately fell to the floor. The 45-year-old Love, Simon [3] actress and Girl Scout cookie-seller extraordinaire [4] looked downright stunning as she walked in front of photographers in her bright blue gown, which had a gauzy, dramatic train. After sufficiently wow-ing everyone within a 20-foot radius on the red carpet, she went inside and later took the stage to present the emotional In Memoriam segment [5]. See all her best moments from the night ahead!
