When I was at Jean George they had this code and I felt terrible overdressed in my dark suit. Sort trousers, Jeans and so on could be seen on the neighbor tables A Client of me visited later and confirmed that no dress code was inforced. Only few hotels have a dress code, mostly old glory and show for wonna-be type guests So would be very unusual if Trump has a dress code. Also at hotels with code itīs mostly only for several parts.
