That's what an Oregon woman says happened to her.
Sandy McMillin says an employee of a Eugene, Oregon, Wal-Mart told her to cover up or leave.
The 51-year-old woman tells a local paper the Wal-Mart worker said the bikini top violated health regulations.
McMillin's lawyer says the experience was embarrassing.
A Wal-Mart spokeswoman says the employee was responding to customer complaints.
But Wal-Mart denies she was asked to leave.
McMillin says she's not giving up on Wal-Mart, but will shop at a different store.
