For Alexa Given and her groom, Tyler Given, it was a complicated process, however.
"We had an Excel spreadsheet of everyone's names and we would count through and we were like, 'Oh my gosh, this is so many people,'" Alexa told Inside Edition.
Tyler could only come up with 11 groomsmen, but they made it work regardless.
"I kept telling him he needed to have more than five because I am going to have 20," she said. "... We got as close as we could."
So how did the wedding turn out? "It was perfect," Alexa said.
