At a time when an abundance of superfake handbags and clothing dupes has made it easier than ever to buy versions of items once considered hard to get, those who value provenance have found a new way to flaunt it: pajamas.

Specifically, pajama sets from small labels in European cities known for being stops on the Grand Tour. Typically made locally with cotton fabrics and in classic cuts associated with men’s wear, the pajamas have for some people become a new souvenir of choice — and a way to signal their discerning taste.

“There is a European-ness attached to these pajamas because they come from heritage stores,” said Laila Gohar, an artist who owns styles from labels in Italy and Austria. “We are seeing women bring them from Europe to America.”

Her collection includes pajama sets from P. Le Moult in Vienna, which start at $247; from Casa Del Bianco in Milan, which start at $120 and are offered in prints like Liberty of London florals; and from Schostal Originals in Rome, which start at 195 euros, or about $204.

Other popular makers include Paris em Lisboa in Lisbon, where pajama sets start at 110 euros, or about $115; and Magniberg, a newer Swedish brand founded by a former Acne Studios designer, where styles start at 292 euros, or about $305.
