Plainly put, not everyone can be a red carpet fashionista -- and at Saturday night's Screen Actors Guild Awards, we saw a couple dress disasters.
The aforementioned "Big Bang Theory" star looked like she belonged in a saloon with her purple and lace gown. Without the lace detail, this could have been a winning look for Mayim.
Other disappointments included Mariah Carey, who wore a black cocktail dress that was nowhere near appropriate for the A-list event and Julia Roberts, whose billowy pink pantsuit looked bizarre once she started walking.
