My BM's will be wearing a Bill Levkoff long navy blue dress. My initial thought was to do tan suits (the wedding is in March..outside ceremony in the hotel courtyard and the reception inside the ballroom). I just started the search for a tan suit and I am not loving the options. I don't really want to do gray, so my question is, would black suits be okay? The ceremony is at 4:30pm. I want it look classy and romantic.
