DH and I have been invited to join some friends at Henley in the Stewards Enclosure. I have never been. My friend said the dress code was "below the knee dress or skirt" for ladies...how strict is this? Does on the knee count? I don't think I possess anything I would say is below the knee, none of the summer dresses I own are short but I would say they are more on the knee than below it IYKWIM.
