Looking for recommendations on what to wear to a casual family reunion/BBQ in Florida over Memorial Day weekend. It's out in the country by a small lake – not by the ocean. Bound to be very warm and humid. I'm thinking chino shorts with topsiders, but what kind of shirt? Any recommended online stores for good chino shorts and tops? I'm on the shorter side, so longer length shorts usually go past my knee and look ridiculous. Looking for something of reasonable length that's not too "old man" looking.
