David Perron's idea to dress up as linemate Ryan O'Reilly sent him to about 20 different stores around St. Louis on Monday before the team's annual Halloween party.
"I had been thinking about it for a couple of weeks, what should I do, how should I do it," Perron told stlouisblues.com. "I was going store to store all morning."
By late Monday, Perron's costume was ready.
