They may look normal, but sometimes it's about the cut, the fit, and how it flows over one's body nicely to minimise one's flaws or flatters one's figure, and how durable the quality fabric can last...that sort. I'm not saying all expensive clothing are like that but sometimes it's worth paying a bit more for quality. Also, there's lesser chance of you wearing the same thing as every other person on the streets.
Anyway, I like simple looking clothes if they're comfy and have the above attributes.
