Thanks for the response, Luv. I REALLY think that would be taking the dress a little overboard! (pun intended!)
And I'm sure some people will gasp in horror, but once we decided NOT to bring any formal wear and bypass formal night. Our tablemates really wanted us to be there, so they actually convinced us to come anyway and we were not turned away! We did wear nice jeans and not tshirts (this was on Carnival in case anyone wants to blast them). My husband was in a wheelchair so he was less noticeable.
And believe me, no matter how good my shoes look, they're still not as comfortable as my tennis shoes!
