January Jones slims down to size six for next X-Men

January Jones had to wear a girdle back in Mad Men in order to mix properly with her co-stars. Back then, she was a size ten.

Now, after a strict juice diet has caused her to drop down by two dress sizes, she still needs a lot of help fitting on Betty Draper’s next series of designer clothes. For her upcoming role in the next X-Men movie as Emma Frost, the 33-year-old Jones shed pounds all the way to a size six.

She explains that she finds her revealing costume in the film to be a challenge saying “in the comic it’s pretty much painted on and she has quite an unrealistic body.”
