Korea is different from the western world, they have a different culture and ways of doing things. Although they also wear clothes that come from american and European companies there are still some taboos. For instance girls can wear extremely short miniskirts but it is totally inappropriate to show shoulders, collarbones or cleavage. The social laws seem to be relaxing nowadays but in some areas of the country it is still considered highly inappropriate. Therefore when coming to Korea try and keep it conservative as you will be working with these people’s children.
You should be able to get away with showing you shoulders as long as it’s not in a strappy top. In summer you can wear lovely floral dresses or skirts. Your shoes should be chosen according to your school. If you’re working at a private academy (hagwon) then go with flat shoes because you’ll be on your feet the whole day. In public schools however you’ll wear slippers inside the buildings so you could wear high heels to work if you choose.
It is always better to put your best foot forward in a new work environment. Your style can become more relaxed once you’ve settled and seen what the other people at your work wear. Generally though the Koreans are dressed to the nines. A lot of foreigners wear jeans to work here in Korea but they keep it formal rather than casual.
What not to wear to work!
Although this outfit is really cute it is not something you should wear to work. Uggs with jeans are OK in winter because it is freezing but not with sweats and t-shirts. You are a professional, try and act like it.
