"I walked in and the lady at the front counter said, 'Hey you're too big to be in this store, I need you to leave,'" Shelby said.
Shelby was with a friend and the time of the incident and had to wait until she finished shopping to leave the store and tell her mother what had happened.
"So she checked out and we walked back," she explained. "My mom came back to talk to them and they were like, 'Oh, we're so sorry!'"
When contacted by the press, the rue21 district manager said they are aware of the situation and are currently looking into it.
In the meantime Shelby's mom had both Shelby and her friend write a recount of what happened to document the incident.
"This made no sense to me," Shelby said. "They should just have more respect, just to refrain from insulting people like me and stuff."
Though the manager reportedly said that rue21 does not tolerate discrimination, neither Shelby nor her mother have been contacted by the store since the incident.
