The athlete wed Mark Caldwell, in Dallas on Saturday, her rep confirmed to the magazine.
"My dress was the very first one I tried on," Patterson told People. "I knew it was the one immediately."
Patterson, 24, also says she knew soon after meeting Caldwell, 27, more than three years ago that he was the one.
"This might sound cliche, but after two weeks of dating Mark, I knew he was completely different from any other guy I've ever met," Patterson said of Caldwell, who is a consultant for Accenture's management consulting group. "Mark is handsome, loving and he makes me laugh. He is a great support system and motivator in my life. I feel so lucky and fortunate that I get to spend forever with my best friend and the love of my life."
The couple, who met at a mutual friend's wedding, were engaged in January.
"Mark and I had the most incredible night of our lives celebrating with all of our close friends and family. We are so excited to start this journey together and so blessed to have found each other," Patterson said.
The wedding reception was held at The Main Room in Dallas.
"Mark and I chose a Southern theme for the koozies [insulators for beer cans and bottles] because of my Louisiana upbringing," Patterson said. "We did black and gold for the Saints inscribed with 'Les Bon Temps Rouler.' " ("Let the good times roll.")
Other koozies had the words "A love brewed down South" on them.
