Mahdieh Mohammadkhani's different outfit in her concert in Germany

As a general rule of thumb, you should dress for the weather. If it is summer, then you can wear tank tops and denim shorts with trainers or flat sandals to keep your feet comfortable in case you need to stand for a long period of time.During winter, it is recommended that you wear jeans with cozy sweaters or coats when going out in cold weather because this type of outfit will keep you warm and comfortable so when the show ends at night, no matter how late it is, you don't have to worry about freezing outside.
