Which dress to wear to a wedding?

I posted about the black and purple already, but the black one just came in the mail today.

Pros to the black: sleeves, I think I look slimmer in it.

Cons: need to find a way to dress it up, maybe a beaded sash?

Pros to the black & purple: more “formal”, longer

Cons: no sleeves, bulky
