I definitely should have gotten a size 7, as it seems my feet have shrunk lately and 7.5 is no longer my standard size. If it is for you though, these are true to their size.
The heel is a little high, but the tiny platform does help and if you're used to stable heels (as opposed to more tapered/spike heels, which I can't deal with) these should pose no problem. I wear them EVERYWHERE. Work, parties, bars, dinner at the in-laws, shopping and they look great with everything, skirts, jeans, leggings. They're pretty dang comfortable, even with my feet sliding around in them a bit. The zipper faces out, which keeps throwing me off, as every other pair of boots I own the zipper faces in, but I think that's supposed to be part of the design and it is cute.
I knocked one anticipatory star off because the fabric seems very delicate and I have a feeling in 6 months I'm going to have a very patchy pair of boots. That being said I'm very glad I bought them and would like them in an additional color (maybe grey?) as well.
