She finds herself on a strange island

Her name was Diana Prince and she was having problems with an old crone.

“I'm sorry, Princess, but I fear you can go no further dressed as you are,” said the crone. "Just as no one can arrive here at our island without first disrobing in the presence of one of our custom officials, neither can one leave without first taking off their old clothing and putting on this uniform."

"What uniform?” said the princess.

"The one I hold in my hand."

"But that's so small!"

"Nevertheless, that's the law."

Diana glanced about.

A room full of three old crones, she thought. I suppose it would be safe.

She took off her dress and reached for the uniform. The very small uniform. The very small and fragile uniform. The almost microscopic uniform.

She slid one leg into an opening.

Pulled it up.

It ripped.

“Damn!"

“Please! No cussing."

"This uniform is no good."

"Nevertheless, you must put it on."

"I can't put it on. It's too small."

"There is no such word as 'can't' in a true superheroine's vocabulary."

"To Hades with it. I'm putting on my old clothing."

"Too late. It's already been destroyed."

"What? But I only took it off a second ago."

"That's the breaks."

"Damn it!"

Diana walked towards what she thought was the exit.

"Don't go through that door," warned the crone.

"To Hades with you!"

"Don't go through that door."

"Don't tell me what to do!"

"Don't --"

Light sparked. The world went dark. Diana walked through the door...

And found herself in another world.
