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.

If you are a 1/2 Size .... go up!
Size: 8, Color: Black, Size: 8, Color: Black
I love it! I wear heels everyday and these heels are great! Very comfortable since the heel is not to large also still sexy since it’s a stiletto! Only down is that they do not have 1/2 sizes and I am a 8.5. I got 8 based on the reviews but I knew better I should have went for the 9. Not their fault so I didn’t lower the rating. Aside from that they are awesome!
