I'm often a size 7, though if a shoe runs tighter, I want a thicker sock or something then I've sized up to 7.5 or 8s. This one I went up a 1/2 size to the 7.5 and I'm so glad I did! Fits great, with just one centimeter or so at the back. I can go with or without a sock. Definitely glad I sized up.
Also so slimming! I was worried this style might make my foot look wide (I don't have wide feet so idk why I was) but it's so cute and slimming on.
