wedding attire

So here's my initial thought for this upcoming wedding. Just so you know a bit about me.. I'm always the understated don't draw attention to myself for being overdone - I prefer to be the classic understated, and very comfortable one at an event.

The pants I have, add a pair of subtle leather open toe heels, and then I'm thinking add the simple fitted long cardigan + a fabulously chunky bracelet. Thoughts?
