CinemaCon 2018: Blake Lively rocks a bow tie while Tiffany Haddish goofs off in slinky silver jumpsuit

Who needs LA? Hollywood's biggest names made their way to Las Vegas this week for CinemaCon -- and the fashion choices were very Vegas-appropriate.

Blake Lively hit the red carpet in a blue tuxedo-inspired mini dress, which she topped off with an orange bow tie. Maybe she's looking for a Vegas side job as a magician?

Dakota Johnson's ensemble was also on the wilder side: The "Fifty Shades" star wore a very vibrant chartreuse number. The ankle-length dress somehow managed to be both conservative and flamboyant -- a tricky feat!

Meanwhile, Tiffany Haddish -- recipient of the convention's "Female Star of Tomorrow" award -- was ready to party in a slinky, sparkling jumpsuit. It was certainly our favorite red carpet look, and it didn't hurt that Tiffany showed it off in a variety of goofy poses. Love that she doesn't take herself too seriously!

Mila Kunis and Kate McKinnon stayed away from flashy outfits, but they still lit up the red carpet with plenty of laughs and hugs to go around. It's no surprise these two funny women are such big fans of each other.

More sightings came from Gabrielle Union, Anna Kendrick and Jack Black. Take a look in the gallery above.
