Melissa Behnken was asked to cover up at the gates of Disney's California Adventure Park
“I was looking at him like, ‘Excuse me? Are you serious?’ He replied: ‘This is a family park. You are showing too much’,”
Behnken, who was celebrating her husband’s return from the US Marine Corps added: “I guess women with large chests are expected to wear turtlenecks their whole lives.
“This was our first family vacation and for me, it was ruined.”
Pictures of Behnken at the park show her wearing a leopard print vest underneath a black lace top.
In a statement to the Huffington Post UK, Disney said: "As soon as we were made aware of the incident, we reached out to Mrs Behnken to address her concerns and apologise.
"We also took appropriate action with the involved cast member," said Suzi Brown, director of Media Relations for the Disneyland Resort.
