Coming from a 17 year old (who couldn't care less about prom or any other school function) while I wouldn't necessarily think of it as evil, I wouldn't call it right. It's kind of a 50/50 thing. You and your husband worked hard for the money to buy something you like. However, it's HIS night, his attire, and he's the one who has to wear it, not you or hubby. I can understand where you're coming from but if he has his heart set on a certain color (as long as it isn't more expensive than the one you chose) then he should get it.
