I (50 M) will be attending an outdoor wedding. Invite called for dress pants/chinos and button down or jacket. Ties are totally optional. Family wedding and they are wanting people to be comfortable and dancing . Dress rehearsal is at a baseball park vibe. I currently have a cast on my leg due to tendon repair surgery. Currently thinking dress shorts with a button down?? But do I wear in the one good foot? Everyone is humored by my current state so unlikely to offend anyone. Please help…..
