I bought 38N, and I wear 7.5 B normally. They are more narrow than I expected, but they will work with very little "margin".  Length wise ok, maybe a cm long. If I were a size 7, these would be too long. I can understand the comments from other reviewers about the sizing being large. Style wise - super cute. I got antique lace color. They are very elegant. These don't resemble Birkenstocks, especially in a narrow width. I wanted a sandal for dresses. Love these!
