How can a girl feel pretty and confident while out in public alone?

That comes from within. It's really that simple. NO ONE can do this for her. But she can start by surrounding herself with those that truly care about her.
The problem with people is that we tend to give too much weight to random opinions. The simple fact is these people don't really even know you! Not like a loved one! Only a loved one has invested enough time in you to understand you as a FULL PERSON both good and bad. She needs to UNDERSTAND she's worthwhile. If she wasn't these people wouldn't love her.
Here's another thing she has to understand. It's a mean world! And that's NEVER going to go away. But that doesn't make her damaged. That makes the rest of the world damaged. There is a lot of fear and and anger in it. Don't let that affect her! Rather be the light in a dark world.

Heels. The inches of confidence. Dress well. Do your hair so you can look at yourself in the mirror and think 'I feel like the shit.'

Uh... F-feel pretty and confident?

I'm not sure what the question is asking. Like, practical advice?

Dress pretty, show some cleavage,
But don't show chicken butt 🤣,
Think positive, don't stare anyone too much...
Be consistent, don't allow your negative feelings to prevail you...
