Regardless of your opinion on The Big Bang Theory, it is without question one of the most successful television shows to ever air. Part of the success of that show has to be credited to Kaley Cuoco.
The show pays her well for her efforts, and will logically continue to do so throughout the rest of her life when you can consider residuals.
Which means she should never be able to struggle to make ends meet. And after looking at this outfit that she elected to rock on the red carpet prior to The Big Bang Theory, she may agree that making sure she consults with stylists is something that she should always put on the priority list.
Either way, she has definitely improved in this area, not only on her successful show now, but just in general on the red carpet and off of it.
