Vintage Peach Party Dress

Inanely cute vintage style party dress. Not sure what brand this is. The tag says Medium but would fit like a 6, I am a size 2-4 and it's unfortunately too big. Would fit mid thigh. (Im 5"2 and it's above my knee) I'm in love with this dress and hate to sell but it just doesn't fit. All buttons are in place and has pockets!! Pictures alter color but it is a true peach color.
