Workers at Fiserv Forum on Friday continued to prepare the pro shop in advance of this weekend's grand opening.
Fans on Sunday can get a first look at the arena and take in a block party outside.
"The block party has been a big selling time for us anyway," said Dustin Godsey, Chief Marketing Officer for the Bucks. "But especially this year, with the excitement around the new arena, thousands of people are going to be down here Sunday."
"We want to give them an opportunity to see all the new gear for this season," Godsey also said.
The pro shop at Fiserv Forum is located on the first floor of the stadium. Fans can see the jerseys, hats and other apparel on display through the building's windows.
It'll be open year-round.
Godsey said the store is meant to look and feel like a high-end retail location, rather than a traditional stadium shop.
He said retail space at Fiserv Forum is much larger than what the team was working out of at the BMO Harris Bradley Center.
"In the BMO Harris Bradley Center, we had 1,600 sq. feet of retail," Godsey said. "We've got 6,000 sq. feet in this building between our four stores and other kiosks."
"We want the pro shop, just like everything else in this building, to be about fan experience," he also said.
