January Jones Underwhelms In YSL

January Jones was one of the many celebrities at the premiere of Jules Massenet‘s Manon at the Metropolitan Opera on Monday night.
Mad Men‘s Betty Francis was dressed in a black Yves Saint Laurent floor-length gown with chain detailing and black YSL peep-toe pumps.
Other than the cutout in the back, there’s nothing remotely sexy about this dress. In fact, it kinda comes off as matronly, which is unfortunate for such a pretty young thing like January.
What do U think???
