Do people think this, with some opaque tights and heels like these would be too casual for a wedding?
The wedding is taking place quite early in the day, in a city, and will involve walking from the ceremony to a fairly stylish restaurant (not sure that's relevant though).
I don't really want to look too party-ish, iykwim. Monsoon stuff seems either too sparkly or too empire line (makes me look pregnant), I didn't spot anything I fancied in Coast, either.
Also a little worried that it's too middle aged. I'm 37, size 16/14 (losing weight though as we speak). I suspect there will be some stylish urban types at the wedding and I don't want to look all frumpy. 
Any ideas?
