Eventbrite, a San Francisco-based company that provides ticketing services for event organizers, wants to make that possible through a partnership with custom apparel company Teespring, the company said Tuesday. Now organizers using Eventbrite to distribute tickets for an event can also design a T-shirt or sweatshirt to go with their event that attendees can order when purchasing tickets.

“If you think about event organizers as businesses, they have a lot more needs than just ticketing,” Eventbrite head of platform Dylan Serota told Fortune in an interview.

A service like Teespring is a well-matched partner for Eventbrite given the flexibility it offers organizers. Because Teespring has built its own T-shirt and sweatshirt operations, its customers can simply design a shirt, set a price that covers at least Teespring’s manufacturing and shipping costs, and collect any profits from the sales. Teespring takes care of producing and shipping the shirts to each individual buyer.

Eventbrite event organizers will get to keep all the profits from merchandise sold beyond Teespring’s own costs, which it quotes during the shirt design process. Eventbrite will take a small fee from Teespring as part of a referral agreement.

The service will be available to event organizers in the U.S., Canada, and Europe, according to Eventbrite.

Eventbrite’s partnership with Teespring is the first online commerce partnership out of about 130 the company has with a other vendors such as software for surveys, content management systems, and software to print attendee badges, among others. “If we tried to do all the things that our organizers want, we’d be spread very thin,” said Serota.

For Teespring, joining up with Eventbrite to let organizers and attendees commemorate an event through a shirt goes back to the company’s roots. Co-founders Walker Williams and Evan Stites-Clayton got the idea while students at Brown University and a beloved local bar was closing down. They wanted to create shirts to express support for the bar and eventually turned their experience into a business.

“At the end of the day, there’s nothing like going to a live event, but an event is finite in duration,” Teespring VP of business development Morrie Eisenberg told Fortune.
