Sasha Obama, 21, stares at her phone as she strolls around USC in crop top and low-slung baggy jeans

Sasha Obama was just a month-old baby when low-waist baggy jeans were all the rage — but that didn’t stop her from rocking the controversial Y2K trend as she took a stroll around her college campus this week.

The 21-year-old, the youngest child of former President Barack Obama and his wife Michelle, looked like the cool college girl as she wandered through the University of Southern California, staring at her phone and occasionally looking up at her surroundings.

As the East Coast — her former home — begins to experience colder weather as the seasons change, Sasha fully embraced the balmy temperatures of Los Angeles by wearing a crop top with her low-rise jeans, leaving the waistband of her underwear exposed. Under the wide hem of the trousers were a pair of sturdy brown boots.

While her outfit was somewhat simple, the former First Daughter, who has embraced a noticeably more bohemian style since moving to California earlier this year, added a bit of fashion flair to the look in the form of chunky layered necklaces hung at varying lengths to her neck.

She also saw sporting statement rings on almost every finger, although she kept her wrists free of jewelry. The student looked like she was in her own world as she made her way across the sun-drenched campus, her attention focused on the screen of her phone, wearing a pair of Apple AirPods in her ears.

She also injected some bright colors into the look with her nails; the long claws were painted bright blue on one side and bright purple on the other.

The finishing touch to her outfit came in the form of a $385 woven tote from JW Anderson, which Sasha wore on one shoulder — while her long dark hair hung in a low ponytail over the other shoulder.

Sasha recently began her senior year at USC after transferring from the University of Michigan earlier this year.

It is said that Sasha spent the summer in New York City, but later moved to the West Coast for the new school year, where she joined her older sister Malia, 24, who moved to Los Angeles to take a job. with Donald Glover on the writing team for his upcoming Amazon Prime series.

Since moving to California, the sisters have been seen together several times – and their mother Michelle has also paid for a trip to visit them in their new hometown.

DailyMail.com exclusively revealed a few months ago that Sasha was dating Clifton Powell Jr., 24, the son of Ray actor Clifton Powell.

Clifton Jr. and Sasha are said to have met after she moved to the West Coast, and he already has a close relationship with the family, having hung out with her sister, Malia, a few times over the past few months.

Sasha’s latest campus outing comes shortly after her father, Barack, shared some fond memories of the late Queen Elizabeth II following her death earlier this month.

In an exclusive interview with the BBC – which aired last week but was only shared by Obama on Monday – the ex-head of state recalled some of the “extraordinary generosity” the late Queen showed to his family, recalling how she allowed his daughters to take her own personal carriage for a ride through Buckingham Palace.

Obama compared the late matriarch to his own grandmother and spoke some heartfelt words about his time spent with the Queen during his presidency, during which he and his family visited Buckingham Palace three times.

Those visits, Obama said, saw Elizabeth leave a lasting impression on the family — and helped forge a special bond between the couple that hadn’t been seen before.

But first, Obama, 61, recalled meeting Elizabeth in 2009 during his inaugural year in office — a meeting where the pair formed a mutual friendship based on the monarch’s surprising fondness for the American, and Obama’s subsequent respect.

“The first time I met the Queen I was visiting London,” the ex-president said in the three-minute video tribute. “She reminded me a lot of my grandmother, which surprised me.”

He continued: ‘Not only in appearance, but also in manner. Very gracious, but also no nonsense.’

The president added that despite Elizabeth’s stately presence, she had a “wry sense of humor,” adding that “she couldn’t have been nicer or more considerate to me and Michelle.”

The meeting went so well, that royal author Tom Quinn in his book “Kensington Palace: An Intimate Memoir from Queen Mary to Meghan Markle” wrote how the Queen “fell in love” with Obama, and before her death “often asked her courtiers if they could get him to Britain now that he’s no longer president.’

Shortly after his and then-First Lady Michelle’s much-discussed stay at Buckingham Palace, Obama said his wife returned to England later that year with the two then-pre-teen daughters, Sasha and Malia.

Obama recalled how the Queen had apparently asked for his return, visibly emotional in the pre-recorded clip.

“Buckingham Palace reached out to me and Her Majesty had invited Michelle and the two girls for tea,” Obama explained.

He further revealed that when Elizabeth met the children, she graciously offered them the unprecedented privilege of taking her personal carriage, which was commissioned for King George III more than 260 years ago.

The stately chariot – gilded with 18th-century gold – is worth millions of dollars and is one of the UK’s most important relics related to the royal family.

“She then offered the girls to ride in her golden carriage across the grounds of Buckingham Palace,” Obama said.

“It was the kind of generosity and consideration that left a mark on the life of my daughter who is still here.”
