Banana Republic Floral Midi Slip Dress size 0

Banana Republic Midi Dress, size 0 (but fits more like a 2-4). Beautiful silky material with a gorgeous floral pattern. MIDI length, longer in the back. Brand new without tags. Tried on and was a little big on me (I fit a size zero, so that’s why I said it fits more like a size 2-4). I am sad that it doesn’t fit because it is such a beautiful dress! Comment for more details or for measurements! Thanks
