The 17th century diarist Samuel Pepys’s collection of French fashion prints casts light on his attitudes to fashion in the period after he stopped keeping a diary, an academic has said.

The naval administrator kept a diary, giving a picture of the official and upper-class life of London, from 1660 to 1669.

Less is known about the second half of his life, up to his death in 1703 aged 70.

Cambridge University historian Marlo Avidon has studied Pepys’s private collection of fashion prints in the Pepys Library at Cambridge’s Magdalene College, where Pepys had been a student.

“It’s really challenging to access Pepys’s later life.

“These prints provide a unique opportunity to consider his attitudes to fashion in this period.”

She focused on two volumes of fashion prints, the Habits de France and Modes de Paris, which comprise more than 100 fashion illustrations printed between 1670 and 1696.

In 1669, Pepys wrote that he was “afeared to be seen” in a summer suit he had just bought “because it was too fine with the gold lace at the hands”.

Finally he plucked up the courage but a socially superior colleague spotted him in the park and told him the sleeves were above his station.

Pepys decided “never to appear in Court” with the sleeves and made a tailor cut them off, “as it is fit I should”.

He went on to buy a print entitled Habit Noir (evening wear) which shows an elite Frenchman proudly showing off very similar lace cuffs as well as plentiful ribbons.

“Pepys would have seen this outfit as pretty risky,” Ms Avidon said.

“This was for a French courtier, and was probably well beyond his budget.

“But Pepys probably did own suits with these kinds of ribbon loops, just not so many as this.

“This is how fashion worked and still works today – you demonstrate your knowledge of style within your means.”

“His father was a tailor, his mother a washerwoman, and throughout his life Pepys was profoundly worried about how he was perceived and took steps to manage his image.

“The diary shows his anxieties as a young adult.

“The prints show that his determination to prove himself, using clothes and cultural capital, continued throughout his life.”

Pepys rose to be the Chief Secretary to the Admiralty in 1673 and was first elected as an MP in 1679.

His initial print purchases and close observation of his superiors in the civil service, detailed in his diary, show him attempting to access lofty social circles, Ms Avidon argues.

“He started to use fashion to solidify his social position and demonstrate his cosmopolitan tastes,” Ms Avidon said. “But collecting fashion prints was also a way to cement intellectual relationships and maintain his scholarly reputation.”

Ms Avidon continued: “I went into this research with a lot of reservations about Pepys, I didn’t like him.

“But the prints offer a much more nuanced picture of him, a more human picture.

“He was fallible and anxious and his actions in response to that anxiety feel quite familiar today.”

French clothes were often viewed in England as being scandalously excessive as they combined luxury silks with over-the-top trim and lace, and huge statement accessories.

“Pepys had a French wife, was friends with French merchants and had a keen interest in French culture,” Ms Avidon said.

“But Pepys also ridiculed people returning from France wearing over-the-top French fashions and he had a preoccupation with French elites being frivolous.

“Pepys felt under pressure to maintain the moral high ground, not just by wearing clothes appropriate for his own social station but also to uphold what was appropriate for his country, morally and economically.”
