Mrs Obama said she regretted wearing it back in 2009 because of the backlash she received from people who felt it was inappropriate for a First Lady to dress like that.
She told BET,
"Because people were like, 'she's wearing shorts getting off of Air Force One. Sometimes I forget I'm the first lady and I'm running around in shorts."
Michelle said she won't wear shorts on Air Force One or out in public again.
