With an eye toward an upcoming final decision on the new uniform, Sergeant Major of the Army Dan Dailey took four soldiers in pinks and greens, along with Army Undersecretary Ryan McCarthy, to a Capitol Hill reception on Wednesday to show lawmakers what he’s been working on.

The latest models included an enlisted male uniform and an enlisted female uniform with pencil skirt, as well as an officer’s maternity uniform worn with pants, according to tweeted photos from the event.

The soldiers also modeled two styles of cover, which are both under consideration.

The newest prototype of the bunch is a maternity option, a green smock worn over the khaki dress shirt that resembles the current blue version for the Army Service Uniform.

A final decision on whether to authorize and field the uniforms is due this spring, Dailey told Army Times in December. That decision would likely be followed by a three-year period to phase it in, allowing enlisted soldiers to set aside money from their clothing allowances to buy the full set, while basic trainees would begin receiving it at graduation.
