From "whoa!" to "oh."

At Monday night's premiere of I Don't Know How She Does It, all eyes were on Christina Hendricks, who showed off her ample cleavage in a pink satin Vivienne Westwood dress.

But it appears that the actress wasn't in the mood to wow the crowds with her curves the following night at an event for Self magazine.

The stunning redhead covered-up in a black turtleneck and frumpy white knee-length skirt.

The Mad Men star recently revealed it's "bizarre" that "people are constantly asking if [her] breasts are real or fake."

In an interview with the Daily Mail, Hendricks, 36, said her famous assets are "so obviously real that anyone who's ever seen or touched a breast would know."
