True to size for me! Though my SA said you just have to try because even every piece in the same size might vary slightly in fit~
That is true, every style runs different. I am normally an 8 1/2 but in Chanel cap toe ballerinas I am a 39 or 9. I just bought the quilted cap toe ballerinas today and I had to take 39 1/2 or 9 1/2. I have a wide foot and the Chanels make my foot look less flat footed
