I bought this bootie in 8M and 7M, it only comes in even sizes, no half sizes. The "8M" is a little to large and the "7M" is too small. I think the sizing is based on European sizes, which means a 38 is more like a 8 and 1/4 and the 7 is more like a 7 and 3/4 (or so).
For reference, I normally wear a US size 8M in a closed toe shoe.
Nonetheless, I kept the "8M" as I can add an insert to make them fit. I bought them in GOLD and they are a total riot.
I plan on wearing them on Christmas with a black or purple velvet long dress. Gold jewelry and purse, of course.
But they will also be a hit for Valentine's Day, a wedding, or any other fancy or goofy occasion. And they come in a multitude of colors!
I definitely recommend them. Just wish they has pointy toes, even though that would detract from the "Victorian" look.
I gave them only 4 stars because of the peculiar sizing.
