Hair and clothing take their cues from the fashions of one's peers, and hence the parents don't get too involved, but Che-ho is simply not a sophisticated enough buyer. If the clothes he buys don't change shape after washing, then they're cool enough to look at but impractical to wear. He's wasted a lot of money.
髮型及服飾牽涉到同儕流行，夫妻倆並不太干涉，但是哲和的購物經驗實在不夠高明，買回來的衣服不是下了水就變形、就是夠酷但不合時宜，浪費的多實用的少。
