13:
There was to be a ball, in celebration of the holiday, Headmaster Dumbledore announced.
And, just for fun, it would be a masquerade ball. There were rules to go along too.
1)The ball is only open to fifth years and up.
2)One's identity must remain concealed for the entire evening.
3)No pins, buttons, or any type of garment may give away the house the student who is wearing them is in.
This, the three decided, would be perfect.
On December first, when Ginny and Luna woke up, they found large, reality flat, interesting boxes on top of their trunks.
Attached to the boxes, was a letter with their name on it, and the words Don't open in public! scribbled on it.
Ginny ran to the girl's bathrooms and went into one of the stalls to open the letter.
Ginny,
This is for you to wear at the ball. Luna got a dress and mask from me too. I'll have two-peacock feathers magiked to my left chest so you'll know its me. See you later on, D.

Ginny quickly tore up the letter and flushed it so that no one could find it. She then opened the box to look at her dress.
"Wow." Ginny breathed.
Her dress, a black and deep red gown, had a plunging V neckline and long sleeves than fanned out at her wrists. Her mask was black and it had two holes in it for her eyes. It stopped just short of her mouth. It fanned out with deep red feathers around the edges, looking as though they were coming from her eyes.
"How much did this all cost?" Ginny thought to herself.

After Luna found her box on the top of her trunk, she slipped into the girl's toilets to open the present. It was from Draco.
She read her letter and then ate the parchment. Luna gasped when she opened her box.
It was a long navy blue gown that laced up at the front. The sleeves were long and fanned out at the wrists, but had a little tie around it for her third finger to go through. This was so that it would not slip while she was dancing. Her mask was black and it had two holes for her eyes. It stopped just short of her mouth. Navy feathers were around the edges of the eyeholes and at the top of her mask.
It must have been very expensive.
