I'm off to a wedding this weekend, but am rethinking the dress I'm planning to bring.
The wedding invitation did NOT say "black tie" but did set a rather oppulent mood (gold and burgundy, embossed text, calligraphy on the envelope, etc.).
Then I just saw on their wedding website it says "formal attire is required". My boyfriend will be wearing a suit anyway, since he can't afford a tux (and it didn't say "black tie"). But now I'm thinking the dress I'm wearing might not be formal enough.
It looks something like this but in pink - Calvin Klein, knee length:

And I was going to wear it with these:

(the shoes are the same material, but more of a peep-toe than a sandle, and they match the actual dress - the pink is the same color)
Thoughts? Is it acceptable, or should I pull out the good ol' 'little black dress'?
