We wouldn't be surprised to learn Christian Siriano's been watching Clueless. When the designer and his date, Alicia Silverstone [1], stepped out for the CFDA Awards [2] on Monday night, the actress was giving us some serious Cher Horowitz vibes in a sexy red gown Siriano created for her. Now we can't shake the image of Alicia in her iconic role rocking that red-hot minidress, making this one look we'll remember long after tonight.

Just take a look. While all grown up, this look's still got Cher's name written all over it, and we have the pictures to prove it.
