Calling that guy “heavy” is just uncalled for. And probably inaccurate. Plus Supergirl’s judgement of what is and isn’t heavy is totally different from ours.

And this is why it’s not brave when you fly around saving people, Kara. Because there’s no difference between flying around aimlessly and carrying fashion-impaired men over your shoulder.
But more seriously:
What is that guy wearing? Checks and stripes? All flesh tone? Such a no-no.
