I agree with Nancy; with your green eyes, a smoky violet shade would be perfect. I have green eyes, too, and I find this shade looks best with mine
When you're using darker colors to achieve a smoky effect, you might want to consider using your your fingertip to apply the color because you have more control over how much/what contours you're applying. Try to keep the violet only from your lash line to just a little above your eye socket.
Hope this helps

Have fun at the wedding!
