In 1975, John T Molly’s book Dress for Success became a national bestseller. It promised the American workforce “scientific” proof that certain clothes could “increase your income” and “boost your status”. It offered searing advice like: “Sweaters give out nothing but negative impulses … they say ‘lower middle class’ and ‘loser.’”

For those with office jobs, the workplace has long been a place where fashion counts. Molly’s book gave rise to ideas like power dressing and the adage about “dressing for the job you want, not the one you have”. But a new casual office culture, spurred by San Francisco tech companies where hoodies are the norm, plus the work-from-home revolution, was supposed to ameliorate some of those pressures.
