WSOP Tournament Rules - Veils get all-clear

Well here they are:

I can't find anything that expressly forbids the wearing of a veil, though there is a limit on how big the logo on the veil can be.

Here's the relevant extract:

29. Tournament participants may wear one item of apparel with a logo no larger than 6 square inches in size. Harrah’s reserves the right at all times, to change the logo size limit, ban the wearing/display of any or all logos, or to ban any apparel or other means of advertising that contains obscene images or words or is otherwise deemed objectionable by Harrah’s. Harrah’s also reserves the right to exclude any individual(s) acting in a disruptive or inappropriate manner.
