Definitely size up a half size due to the pointed toe. I wish I would have but too cute to return not knowing if they will restock.
I wear a size 6 usually those 6s are kind of big on me (these were a perfect 6 because of that but you may want to go up a half size). I love wearing these with lazy day leggings and a tunic-type top. First pair of mules and very happy to have a wintery looking shoe that isn't a boot (since we get few cold days in the south).
I got them a size 7 and usually am a 6.5 I would recommend getting a half size up
