Yes (Owl Outfit)

"Ok you convinced me." Hermione said and thus she took the Owl Outfit causing Ginny to grin to this.

"That's my girl." Ginny said and thus went off to get ready for the party.

(Later)

Hermione was looking herself in the vanity mirror adjusting the costume to the best of her abilities. "Bloody hell I look like a whore." Hermione said in mock scolding to herself as she looked herself over.

"Yes but you're a mighty smart one." Ginny added as she appeared wearing her Phoenix Costume which was just as bad as Hermione's own costume.

"Ginny!?" Hermione gasped as she saw the outfit Ginny was wearing.

"Don't worry we'll be drawing all of the boys towards up, and maybe a few girls as well." Ginny said with a small wink before admiring herself and Hermione in the mirror.

Hermione had to admit that she has never been so turned on in all of her life. She was about to expose herself at a Halloween party wearing this. She could already feel all eyes on her watching her gasping pointing whispering and insulting her calling her a slag. But more so she could even picture the cat calls that showed off how attractive she was. It took all of her will power to not use those images for masturbation right now.

"Ready to go?" Ginny asked as she smiled to Hermione.

"I suppose. After all I'm already wearing this." Hermione said and thus the two witches were off well past the point of no return.
