There is no general dress-code or any other clothing limitations in Georgia, except for when you visit religious places like Churches or Monasteries. As a mark of respect women should cover their legs, head, and shoulders. Men are required to cover their legs so if you want to go into churches or monasteries it’s a good idea not to wear shorts on those days. Apart from that Georgia is largely less formal than Europe and the UK and you don’t often see men in jackets and ties.
