The Oklahoma City Thunder returns to the Payroll Center this week, with attendees receiving a mix of playoff shirts this season.

Each ticket holder will receive a free T-shirt that will depict the crowd in blue and white stripes in Game 5 on Tuesday. Most fans put on their shirts right away (if you don’t, you may encounter huge shirts and add pressure).

During the season’s playoffs, the Thunder also continued its relaxed Jumbotron Antis, an antic designed to keep stressed fans wearing playoff T-shirts. The camera pan was given to attendees, who did not wear a shirt and bursting boo.

Here’s what you need to know about Tuesday shirts.

OKC Thunderbolt Playoff Shirt Design

The playoff shirts for this season are blue and white, and for Game 5, fans will get another chance to playoff design. The shirt says "Playoff 25" and "Oklahoma City Basketball EST. 08." They are thunder blue with white letters or white with thunder blue letters.

Each shirt also has the River Wind Casino logo on the left sleeve.

You can't choose a shirt; each section has a different colored shirt.

Fans are encouraged to come early, put on their shirts, and sit in their seats by 8:10 pm, and the team is welcomed on the floor before Tipoff.

Why do NBA teams make playoff shirts?

For the Thunder, the tradition of offering 18,203 fans with shirts during the NBA playoffs is a tradition that goes back to the team's first playoff victory at OKC 15 years ago by the team's Los Angeles Lakers who beat Kobe Bryant in OKC. In Game 2, the prank continued as the Thunder handled the Grizzlies 118-99 on Tuesday night.

When tradition started throughout the NBA, but look at the 2007 Warriors Run, you can find some glimpses of the beginning. At the time, it was the Warriors' first playoff debut in 13 seasons, and Warriors executives wanted to "make the first playoff game special."

So they printed shirts for every fan in the arena and have continued tradition in every family playoff game ever since.

Need to wear a shirt?

You don't need to wear a shirt in the game, but if you don't want to face peer pressure, it's better to wear a shirt.

Even the Oklahoma City Police Department made a joke, saying, “We’re watching.”

If you don't have an autographed shirt (either blue or white), you may be worn on giants and booed by fans at home and at home. The camera pan was given to attendees, who did not wear a shirt and bursting boo.

For a long time, Thunder fan Juan Guerra hasn't missed home games, and in Game 2 of the NBA playoffs, he didn't match his dress code. Center Isaiah Hartenstein grabbed a playoff shirt and hung it over Guerra's shoulder as fans booed and tried to pressure Joule into their shirt.

"He put on a neon shirt, I saw it, just think he did it on purpose," Hartenstein told theukhohou ask.fm/. "You can't wear a shirt too cool."

From then on, the goal is to choose people who don’t wear shirts and become a playoff ceremony.
