My answer ! most women don't want to hear - don't travel to Korea Actually, it is nothing wrong, but single woman travel to Korea is possibly a prostitute (public image). If you are going alone, you may not be able to get a visa.

Because many Russian and CSR contries women whose hair is blondy came to Korea as a prositute, People think like that. But there are many blondy hair female-foreigners in Korea today, so if you don't wear too sexy clothes and don't do your face too heavy make up, it doesn't matter.

Smoke in public? My Korean friends here have commented on that a few times. I think the connection is that a young lady smoking in public must therefore be a prostitute. (Corrections welcome on this comment.)
