Why do women get mad when the guy is better dressed than she is?

When I go out, I find out what type of place we are going, talk to my partner ask what he is wearing, try and dress to for the occasion. But the reason we get angry, go into the shops look around in the men department, the clothes look good and smart, even the causal clothes look good. You go into the t, some of the clothes are rubbish, it is hard to pick a good dress and outfit, sometimes it look good on the rails but not on you. So that why we get angry because a man look good when they are going out.
