I bought a jacket the other day. The main colour is green and the jacket itself really suits the climate of for example Iran. I intend to travel in Iran for two weeks. Is it ok?
You will be ok wearing green or any other color in Iran.
Dress attire for men is similar to that in Europe but the dress code for men in Iran prohibits short trousers and short sleeved shirts and t-shirts. Although Iranian men are not dressed in shorts, they will almost certainly wear short sleeved shirts and t-shirts. Sandals and flip flops without socks are acceptable for both genders and make no problem.
