At FPC Bryan, Ms. Holmes, known for wearing black turtlenecks to mimic Steve Jobs while running Theranos, and, during her trial, sporting heels, sheath dresses and a diaper bag, will wear prison-issued khaki pants and shirts in pastel green, gray, or white with athletic shoes that must not exceed $100 in value.

She will not have any internet access but can buy a radio ($31.75) or MP3 player ($88.40) from the commissary. All music must be “non-explicit,” according to the prison’s handbook.

FPC Bryan offers leisure activities including music programs, “table games” and movies, according to its handbook. Arts and crafts are available, including beading, knitting, paper art, crochet and ceramics. A crochet needle costs $1.30 and yarn is $3.55 at FPC Bryan’s commissary, according to the handbook.

Inmates are allowed to access an outdoor “recreation yard pavilion” but must return to their dorms for head counts that occur five times every 24 hours.

Counterfeiting or forging documents and conducting a business are against the rules. Ms. Holmes admitted to falsifying pharmaceutical reports to solicit investors while testifying in her trial.

Other inmates at the prison camp include Jen Shah, a “Real Housewives of Salt Lake City” star who is serving a five-and-a-half-year sentence for wire fraud related to telemarketing. In a blog post from March about her first few days in prison, Ms. Shah described difficulty operating the phone system, which uses account numbers, and noted that not many people were nice. Breakfast was instant oatmeal, an apple and a slice of wheat bread with jelly, she wrote.

Lea Fastow, a former executive for the collapsed energy company Enron, was incarcerated for tax fraud at FPC Bryan for 11 months in the mid-2000s. Jenna Ryan, a participant in the Jan. 6 attack on the U.S. Capitol, spent 60 days there. And Michelle Janavs, daughter of the Hot Pocket co-founder, served five months for her association with the “Operation Varsity Blues” college admissions scandal.
