The obvious answer is gray or charcoal, but I'm having a hard time finding a dress I love within my price range that is this color. I have a gray sweater dress but I don't think this is appropriate for a wedding. The wedding is in Florida next month, dress code is casual. I want to match my husband but can I do this by wearing a different color? Thanks in advance!! We have been to lots of weddings and always wear something that compliments the other and looks good together- we enjoy doing this! It may be a 'high school' thing for you but we have fun with it.
