Sorry for all the clothes posts!

I'm going to a wedding this weekend that DH is in, so he is wearing a tuxedo.

The bride is wearing a big bedazzled princess dress ..with elbow length gloves and cowboy boots. Don't ask.

I sent her a picture of a cocktail dress I had and asked if I could wear that, she told me it was "too dressy" and to wear a sundress. I'm scared to show up in a sundress and look stupid with DH (although we won't see each other most of the night).

If she said "wear a sundress", is this appropriate? She suggested I wear cowboy boots, too.
