What are your thoughts on dressing for comfort vs fashion?

This will sound so immature so please bear with me, but there is a super hot girl in my class and I’m honestly a jealous of the attention she gets. Not aimed at her, she is lovely, but just wish I got more attention. I’ve asked guys what makes her attractive, and they all said her style.

We both look similar but she wore a grey turtleneck sweater, black leather pants, and boots today. I wore t-shirt and shorts, pretty much like everyone else.

Did I mention it was almost 90F and humid? Everyone was absolutely dying of heat and she looked perfectly comfortable the whole day!

Honestly, the outfit looked great on her, and I know something similar would look great on me. Should I do it? Sacrifice comfort for fashion?
