From the official USMC website:
Recent headlines in the media have created confusion regarding a Marine Corps uniform item, the male dress cover. Some in the media have implied that the President of the United States directed a change in this dress cover.
Commandant of the Marine Corps Gen. James F. Amos said, “the President in no way, shape or form directed the Marine Corps to change our uniform cover.”
While the Marine Corps Uniform Board is currently looking for a new cover, or cap, for female Marines because the current manufacturer is going out of business, there is no intent to change the current male Marine dress cover.
A survey released by the Marine Corps Uniform Board eliciting input from Marines in regard to uniform items, sought opinions about the “Dan Daly-style” cover.
Pictures of male Marines wearing this cover were included in the survey material. This is standard practice while conducting surveys. For instance, when the Marine Corps transitioned to the current MARPAT camouflage design several years ago, surveys included a number of proposed cami-patterns and additional uniform options.
“The surveys often contain photo illustrations that portray what a uniform article might look like when worn by a Marine,” Col. Todd S. Desgrosseilliers, Marine Corps Uniform Board president, said. “This is a very standard practice. While there was never any desire or intent to change the male Marine dress cover, the feedback we have received to maintain this iconic cover has been heard, loud and clear. "
Surveys conducted by the Uniform Board serve to inform the commandant, who has the final say on all changes to the Marine Corps uniform.http://www.hqmc.marines.mil/News/NewsArticleDisplay/tabid/3488/Article/153089/marine-corps-not-changing-male-dress-cover.aspx
