I mean, I recently realized that Superman and Spidey's tights are a practical thing: they wear their costumes under their civilian clothes.
Now as men's fashion is predominately covering normally, they can get away with full bodysuits. But if Superman wore Hawaiian shirts and bermuda shorts, he'd either need to keep the rest of his costume in his pockets or start showing skin.
It's the same thing for female capes too. Batgirl (and Batman) tend to rush off to their hideouts and change. They also lack superpowers of their own that is not preptime, so covering up and armoring up a little is a good idea.
And lastly, let's look at Supergirl. She's a modern girl and likes to wear skirts that show some leg and the odd top that shows some cleavage and arm. So unless she wants to have a very different type of wardrobe malfunction, probably a good idea to go with that a one-piece leotard instead of something more modest like this. Unless she wants to flash her secret identity to a boy when she meant to show the goods.
