After that day, Dipper and Mabel went to a shop that was named "Natalie's dress shop for boys and girls". Dipper and Mabel's aunt owns that shop.

When they went in, their aunt was surprised.

"What can I do for you?" She asked.

"Aunt Natalie, can you give us the best tuxedo and the best dress? We need it at the party and our Grunkle Stan has no enough money." Dipper replied.

"Sure, just pick one. The tuxedo is in column 2 and the dress is in column 1." She replied.

"Thanks Aunt Natalie!" They both said in unison.

While Mabel was busy, Dipper was choosing a tuxedo until someone bumped into him. It was Pacifica.

"What are you doing here?" She asked.

"Just choosing a tuxedo." He replied.

I'm just going to the mirror to look on myself. Your bow tie is unfixed, let me fix it for you." She said.

*after fixing it*

"There you go." She said.
"Thanks Pacifica." He replied.
"Now I better go and pay this dress." She replied.

*at the counter*

"Dipper, is this your girlfriend?" His aunt asked.

"No aunt, she is not my..." he said but being cut-off by Mabel.

"Pacifica, you're here?" Mabel asked.

I'm just buying a dress for tomorrow." She replied.

"By the way, I have to go, bye." She said.

While she was walking away, Dipper was smiling.

"Hey bro, did I missed something?" Mabel asked.

"You missed a lot Mabel." Dipper replied.

"So you guys know her. She is my best costumer." Her aunt added.
