So many requests for fashion help lately!

We are attending a wedding in Orlando in October. The invitation labeled the event as "semi-formal". Here is the dress I am planning to wear.

1. Which shoes do you prefer? (The second pair is a dark teal.)
2. What should I do for jewelry? I usually wear the same basic necklace and earrings every day, so I don't have a ton of special occasion jewelry. I don't know what style of necklace would work best with this dress, so I am open to general ideas or specific suggestions. (I am open to purchasing some pieces, but only in the Target/Kohl's/etc. price point.)
