The Best & Worst Dressed at the 2015 SAG Awards

Sunday night's SAG Awards was a big night for fashion, but which stylish stars came out on top, and which ones completely missed the mark?
Fashion expert and The Real co-host Jeannie Mai joins ET from Miami -- where she co-hosted the Miss Universe Pageant -- and is breaking down the best and worst dressed of the night.
Menswear with a feminine twist was a big theme, with both Emma Stone and Julia Roberts making our best dressed lists in their suit-style creations. Emma looked fantastic as usual (even if the sheer train nearly killed Naomi Watts) in a Dior couture tuxedo gown, while Julia rocked a shapely Givenchy tuxedo-inspired jumpsuit. Both looks were age-appropriate, and definitely fun, unexpected choices for the red carpet.
Rounding out the best-dressed is Jennifer Aniston in a plunging vintage Galliano gown, which showed off her famous yoga-toned body to perfection thanks to its slinky design. She upped the look with a body chain necklace, highlighting her sexy cleavage even more.
But they can't all be winners on the red carpet.
Most glaringly, Rosamund Pike put it another disappointing awards show appearance -- after her ill-fitting Vera Wang gown at the Golden Globes -- in this frumpy big black Dior mullet dress.
"It looked like heavy tissue paper on her body," Jeannie comments, also noting it's unflattering, oversized shape.
