Greta Stud Embellished Mary Jane Flat

[This review was collected as part of a promotion.] I have this flat in at least 5 different colors, and they have all been super-comfortable and true to size. I normally wear a size 9 consistently across styles and brands, but for the Greta Deep Blue with silver studs, I have to wear a size 10 for the same fit. I originally bought the 9 on sale, returned that and tried another 9 just in case it was that specific shoe, but no, it was equally small. The 9.5 fit ok but still tighter than my other Greta colorways, and I had to go up to 10 in order for it to fit the same as the 9's in other colors. Not sure why, but that's how it is. Still, super-rare nowadays to get a comfortable, full leather flat (lined and exterior), so I'm going to keep buying them.
