Brittany Minder is sharing her story because she doesn't want anyone else to suffer the pain and humiliation that she did on a night meant for celebration.
Minder's search for the perfect prom dress took her all the way to Canada, but when she showed up at the senior prom in her brand-new gown, she was told she couldn't come inside.
"In my opinion, I feel that it is because I'm bigger chested and there is more cleavage that you can see, and there's nothing I could really do about that," she said.
According to the school's dress code, strapless dresses are allowed as long as cleavage, midriff and lower back are covered.
"It was blatant from the start that the school was not being fair in how they were enforcing that rule," said Minder's dad, Gary Minder.
Minder's parents have no problem with the rules, but say their daughter was singled out for having a large chest.
"All women are not created equal, and you can not compare a golf ball to a grapefruit. It ain't gonna happen," Kim Minder said.
Gary Minder wonders what kind of dress the school would have found acceptable.
"A girl like Brittany should not have to go to a dance in a burlap sack because she's large busted," he said. "It's ridiculous."
A school district spokesman said if a student's appearance does not meet the dress code, staff members will help them come up with a solution that allows them to attend the event.
In Minder's case, she wasn't allowed in the prom until she covered her cleavage with a shawl. She only stayed for about an hour.
"I felt self-conscious and they took the magic out of the night," she said. "It was tough being there after all that happened. I didn't feel comfortable. I already had a blow to my self-esteem. I didn't really want to be there anymore."
Minder said her gown was designed for a woman with a larger bust, but now it's a painful reminder of a horrible night and she's not sure what to do with it.
"An important night of my life was ruined, and there's no way I can gain that experience back," she said.
Minder said she's worn dresses with a similar neckline to other dances without any problems. Her parents say they want a public apology.
