Very clever to consult a dictionary but decent sounds more downgrading than you probably realize. If we would hold a survey among people and ask them what they think DECENT is, you would probably get another answer.
Shown them this $425 cashmere waffle and tell them how it's made... Ask again: ''Do you think this is decent?'' They'll probably ask you whats wrong with you and tell you that it looks and sounds more like TOP QUALITY!
