the belt looks a little too heavy or a little to high. Otherwise very cute and love the sandles. If you have thin ankles like you do, i think its fine to have the ankle strap.
I like the top part, but the skirt is too short. The belt cuts the line, and makes the skirt seem even shorter. Hard to tell from this angle, but the ankle strap has got the be cutting your legs off visually, and that's not flattering.
Pic's perspective isn't the best. If the fit is right, the length not too short, it's fine. The color tho isn't the best for your skintone. The sandals appear perfect w/ the dress tho.
