Our wedding is going to be semi-casual and will be outdoors in Las Vegas in June. My dress is a knee length strapless white dress. my matron of honor is wearing a watermelon strapless knee length dress and carrying orange gerbera daisies. My other 2 bridesmaids are wearing tangerine knee length dresses and carrying pink gerbera daisies. I am completely stressing about what to have the guys wear!! I want to keep it kind of casual so they will be comfortable (and cool!!). I was thinking about maybe doing the white hawaiian wedding shirts, but I wasn't sure of what color pants and shoes to go with them that wouldn't clash with the watermelon and tangerine theme!! Does anyone have any ideas of what would look nice for them to wear, without being too formal?? This is really the only part of my wedding that I'm stressed about!!
