Is My husband Economic? 夫は経済的なのか？

My husband ordered a navy blue dye for clothing on Amazon site. 夫は服用の紺色の染料をアマゾンで注文した。 He is going to dye his worn-out polo shirt. 彼は着古したポロシャツを染めるつもりだ。 When he dyed his pants in the bathroom before, it was a mess because the floor partially got stain. 以前風呂場で彼がズボンを染めた時は、大変だった。風呂場が一部分シミになったから。 He said that dying his old clothes is economical because he can revitalize his clothes, which leads to eco-friendly. 彼は、古い服を染めるのは経済的だという。古い服をよみがえらせることができる。それは環境にもよい。 However, considering the cost of dye, the process and damaging fabric, I don't think it can save money. でも染料のコストや手間や布にダメージを与えることを考えると、私は経済的だとは思わない。 Besides, he drains dye. その上、彼は染料を排水する。 If I were him, I would buy new clothes, but I won't throw away old ones. もし私が彼だったら、新しい服を買って、古いのは捨てない。 I would wear old ones at home, and wear new ones for going out, which might be more economic. 家で、古いのを着て、外出時は、新しいのを着る。その方がもっと経済的だ。 He doesn't have a sense of economy. 彼は経済観念がない。
