Going to a different country who has a different culture will surely have different dressing perspective and style. Traveling to a foreign country will excuse you at times on what you are wearing. But when you will stay there to work or for a long vacation, it is better you learn their fashion and way of life so that you can adapt and be immersed in a local experience that surely you will not forget. If you will work here, it is important that you know first something before you buy. Not just clothing but also makeup.
As one person is different from the other, there are differences even if we wear same clothes and accessories from the top to the bottom. But one tip that you should do here is to cover your upper part. Korean women can wear the shortest skirt or shorts or dress but you cannot find one who will wear top revealing clothes even in the time of summer. They are allowed or forgiven when you are at a foreign bar, though. One tip before you come here and stay for a long time, regarding shoes and bras.
It is better for you to bring your own as you cannot find easily your sizes here if your bra size is different from cup A or B. in regard to the shoes US sizes of 8 or 9 can be hardly seen here. Western shopping stores can be found here, though. If you are wondering about food, as they are delicious but just be careful with the spicy ones.
