Mandy Moore just committed a sartorial sin, and she's ready to confess.
On her Instagram Story, the This Is Us star posted a pic of herself in her dressing room and shared details about her fashion faux pas. She captioned the mirror selfie, "Just noticed my underwear was upside down all day. Note to self: Don't get dressed in the dark. (I was trying not to wake up @tayloedawesgoldsmmith.)" Yep, been there.
