Last week,  43-year-old Madelyn Sheaffer of Independence, Missouri went to a water park with her family, wearing  a bikini. She was asked to leave. 

Madelyn wore a STRING BIKINI to Adventure Oasis Water Park.  She says she recently lost one hundred pounds  and was ready to show off her new bod.  The park workers were not ready for her.

Watch this animated story about the whole affair.

Madelyn was very upset when the park told her she had to either cover up or leave because the bikini was too revealing.

She says the only reason they said that is because she's FULLER FIGURED and in her 40s.  Quote, "I could see a handful of other girls half my age wearing the same size swimming suit and not being singled out."

Madelyn argued with the staff, and they ended up calling the cops, who escorted her out of the park.  She's filed a discrimination complaint against the park with the city.
