Genesis 38:14-15

And she put her widow's garments off from her, and covered her with a vail, and wrapped herself, and sat in an open place, which {is} by the way to Timnath; for she saw that Shelah was grown, and she was not given unto him to wife. {an open...: Heb. the door of eyes, or, of Enajim} When Judah saw her, he thought her {to be} an harlot; because she had covered her face.
