I know its cheap to buy stuff in Vietnam. But honestly I don't want to buy any as we have plenty of clothes already. We are visting Hanoi, Sapa, Halong Bay, Hue, Hoi An, Ho Chi M and Mekong Delta. We are an active family of four. Teenage daughter wears short shorts, is this acceptable in cities, villages etc. What is appropriate to wear out to restaurants, or on tours. Son lives in denim shorts and singlets. Is this appropriate? What about visitng temples etc. Are there more appropriate attire?
