Ex-Biden appointed nuclear official Sam Brinton ditched their usual colorful frocks for a more “traditional” look of slacks and a T-shirt Friday, less than 24 hours after being released from jail over grand larceny charges.

Exculsive pictures obtained by The Post show the non-binary former White House official — who goes by the pronouns they/them — beaming in public while stepping out for the first time since being arrested on May 17 over accusations they stole a Tanzanian fashion designer’s dresses and luggage.

Brinton carried two shirts and was dressed in a maroon V-neck and black trousers to leave the home they share with husband Kevin Rieck in Maryland.

The 35-year old is out on $5,000 bond in connection to allegations they stole clothes made by designer Asya Khamsin.

The designer and her attorney confirmed to The Post federal agents questioned her about her luggage and colorful dresses which went missing after she stopped at the Ronald Reagan National Airport in Washington, DC during a 2018 trip.

Khamsin said she thought her belongings were gone for good until she saw her clothing on the ex-Biden official, who made international headlines for stealing the luggae of two other women from airports in Las Vegas and Minneapolis.

Brinton was initially booked in a Montgomery County jail in Maryland and flagged as a “fugitive from justice” in connection to the latest case.

Jail officials told The Post that Brinton, who identifies as non-binary, is facing Grand Larceny charges and was housed in a men’s area of the facility for about two weeks, as inmates are assigned to jail based on their sex at birth.

Brinton were extradited Thursday to Arlington, Virginia and appeared in front of a magistrate judge before bonding out, jail officials told The Post.

Brinton was first caught red-handed on video taking a woman’s Vera Bradley luggage worth $2,325 at the Minneapolis-St. Paul Airport in Sept.16, 2022. They were seen with the suitcase while traveling in Washington, D.C. on Sept. 18 and Oct. 9, investigators said.

Brinton also pleaded no contest for stealing luggage at the Harry Reid International Airport in Las Vegas in July 2022.

The 35-year-old was working as the deputy assistant secretary for spent fuel and waste disposition at the Department of Energy’s Office of Nuclear Energy when they committed the fashion crime, but has since been fired.
