Saturday's 2016 SAG Awards was full of fashion surprises, including a handful of usually stylish A-listers who shockingly got it wrong this year with unflattering choices.

But first, let's start with the celebs who were stunning at this year's ceremony!

The Danish Girl actress Alicia Vikander not only took home the Best Supporting Actress award at this year's ceremony for her role in the critically acclaimed film, but she was a big winner on the red carpet as well. Alicia, 27, sparkled in a glittery Louis Vuitton number, that managed to dazzle without being completely over-the-top.

Viola Davis was also a standout thanks to this lavender Zac Posen dress, which she also clearly felt great in. The 50-year-old How to Get Away With Murder star oozed confidence -- and looked slimmer than ever -- in the designer gown, flashing an equally radiant big smile.

But when we're talking about a truly ageless knockout on the red carpet, nobody beat Marisa Tomei. The Empire star, 51, surprised in this slinky green Zuhair Murad design, putting celebs half her age to shame.

Though obviously, they can't all be winners on the red carpet.

The worst offender of the night is undoubtedly January Jones. While known for edgy styles, the 38-year-old former Mad Men actress took it a step too far in this drapey Schiaparelli dress, which has to be her worst red carpet showing ever. It's hard to find a dress that's unflattering on the beautiful blonde, but alas, here it is.

Demi Moore, 53, was also not in top form on Saturday, sporting a bizarre hairdo featuring two long bangs. Her super sheer black dress was also a big miss, doing absolutely nothing for her slender figure.

And, of course, it pains our hearts to see the usually flawless Julianne Moore make our top three worst dressed of the night, but the Freeheld star's spectacularly bad Givenchy choice had her standing out for all the wrong reasons. From the tube top wrapping to the blinding lime green color, the 55-year-old actress' dress was a definite candidate for the worst at the SAGs.
