Hope nobody minds me bumping this thread up. I tried on one of the new heeled loafers in Size 37 (I usually wear a 37 but I've never worn Gucci before). It was really loose but I didn't have the chance to ask an SA for a smaller size to try because I was in a rush. I can't go back to the store as I live very far away and have to take a flight. How much should I size down? Half a size? An entire size?
