Tina Fey’s farewell to David Letterman involved taking off her dress

Last night, as part of her final appearance on The Late Show With David Letterman, Tina Fey revealed what’s really under most women’s dresses: Spanx. 

As a tribute to the departing host, Fey offered Letterman her dress after stripping down to a very special edition of the body-shaping undergarment. Fey employed the two-layer Spanx approach, a smart move on her part. She also knows how to start a hashtag.
