I love this shoe!  I tried it on at Macy's and looooved it!  I actually  bought the wrong size on Amazon and had to return them but i will definitely get them again in the correct size!  Because of the patent leather they fit really snug so i'd go with your size or just a 1/2 size below your normal size.  These make your legs look long and gorgeous move over boots I believe these pumps were made for walking the streets of our city and the hallways at the office!  Jessica's shoes are so beautiful and fit great.  Work it girls!
