Beautiful!
Size: 8, Color: Haze Blue, Size: 8, Color: Haze Blue
My daughter got engaged in these shoes and walked all around Paris in them the day of. In all of her engagement photos the first thing everyone notices is her shoes! They are a beautiful powder blue and matched her dress perfectly. She reports they are comfortable and fit true to size. She even purchased another dress when we returned to match them just so she’d have more opportunities to wear them. I can’t imagine anyone would be disappointed in these.

SIZE UP IF YOU ARE A HALF SIZE!
Size: 8, Color: Black
If you are a half size DEFINITELY size up! I am a 7-7.5, but in heels I’m usually a 7.5. I ordered an 8 and it fits perfectly!! They are super super cute but surprisingly not as comfortable as I thought considering it’s a pretty small heel. It’s not unbearable but I would keep that in mind if you’re planning to wear them standing for a long period of time. I didn’t see many reviews about people with half sizes except one and I listened to that one review and I’m very thankful I did. So PLEASE size up half a size.

These run big. I am a true size seven and need a six and a half which is not offered. Beautiful shoes! So disappointed!
