In The Big Lebowski, released in 1998, Jeff Bridges's Dude drifts through Los Angeles in a bathrobe and a battered Pendleton cardigan. Pendleton says it debuted that sweater as the Westerley in 1974, and it has become shorthand for a man entirely at ease. That ease is the story this season. Esquire UK's SS26 trends report says designers proposed pyjama dressing for daytime, with silk matching sets, robe jackets and slipper-inspired footwear, and British GQ's spring guide, dated 4 April 2026, has a whole section called Pyjama Party. I like the idea, as long as you start at home. Zimmerli was founded in Aarburg, Switzerland, in 1871 by Pauline Zimmerli-Baurlin, and won gold at the 1889 Paris World's Fair, so the Sea Island cotton-jersey pyjama set in navy has history behind it. TEKLA started in Copenhagen in 2017 with bedding, and the striped organic cotton-terry robe in blue is the sort of thing you wear at breakfast on a Sunday. Derek Rose's Sicily 1 linen set in beige is my pick for summer. What I would skip is the TOM FORD two-pack boxer briefs in white if you are shopping for something to wear around the house, because they are underwear, not a lounge outfit.

Pyjama trousers are the easiest way into daytime sleepwear, because a pair that is cut well just looks like a loose trouser. Derek Rose is the brand I trust for this. The Rose family entered menswear manufacture in 1926 with Jack Lewis Rose, his son Derek joined in 1953, and the company has made its clothes in Congleton, Cheshire since 1975. The Basel stretch-modal pair in black is dark enough to pass for a casual trouser, and the Arran 20 striped herringbone brushed-cotton pair in blue is the one to keep in the house. CDLP, started in Stockholm in 2016 by friends Christian Larson and Andreas Palm, is known for lyocell instead of cotton, and the straight-leg lyocell pair in black has a drape I find hard to resist. TEKLA's straight-leg organic cotton-poplin in navy is crisp and holds a line. Try these with a plain white tee and loafers, then keep the sleepwear top for bed. What I would skip is the Derek Rose Braemar 32 cotton-flannel pair in navy for a warm climate, since flannel is for cold floors.

Soft accessories are where this look gets practical. Falke was founded in 1895 in Schmallenberg, Germany, by Franz Falke-Rohen, a roofer who knitted seasonally, and it is still family owned and run, which is why I trust the Falke No. 9 Pure Fil d'Ecosse three-pack in brown for socks that look right with loafers. Loro Piana, founded as the current company by Pietro Loro Piana in 1924 in Quarona, is known for fine fibres like baby cashmere, so the Ivy cashmere baseball cap in brown is the one to go for if you want a cap that feels soft. William Lockie's ribbed cashmere beanie in black comes from the Hawick house that set up production in 1874, and Berluti's cashmere beanie in brown is a quiet, warm winter hat. TOM FORD's leather-trimmed cotton-twill cap in black is the sharper option for a trip to the shops. Wear the cap with the pyjama trousers and a sweatshirt. What I would skip is the LOEWE x Louis Wain Futurist Cat baseball cap if your outfit already has a pattern, since the cat will compete with it.

The final grid is cold-weather and desk-friendly. Brunello Cucinelli founded the company in 1978 with colored cashmere knitwear, bought a ruined 14th-century castle in Solomeo in 1985 and made it the headquarters, and that offbeat sense of craft shows in the wool and cashmere-blend baseball cap in cream. Loro Piana's linen baseball cap in beige is for summer, and the Sottile ribbed wool, cashmere and silk-blend socks in blue are a thin pair for loafers. Falke's Finest two-pack of ribbed cashmere-blend socks in navy are warm without bulk. Mr P., Mr Porter's own label, brings the shearling scarf in black and the logo-appliqued fringed cashmere scarf in charcoal, and both suit a coat over lounge trousers. TOM FORD's ribbed silk socks in blue are for people who like the idea of luxury at ankle level. Try one cap and one scarf in matching tones. What I would skip is the Falke SK2 ski socks in multi on any day you are not skiing or walking in snow, because they are made for boots.

What I take from the Dude is that comfort and polish are not opposites. The Dude's cardigan was worn out and his robe was ordinary, and he still looked like himself. Esquire UK ties this season's pyjama dressing to a broader shift toward ease and elegance, and I think the sensible reading is to buy in layers. Start with one good set, such as the Zimmerli or Derek Rose, because you will wear it most. Add trousers you could take out of the house, then socks and a cap in quiet colors, and finish with the scarves. Keep the palette tight, navy and brown and charcoal, and wear one soft thing at a time with a sharper piece. A pyjama trouser with a crisp shirt works, and a cashmere beanie with a plain coat works better. Then go back to the couch.

Staying in goes better when what you put on is soft and slightly considered, and this last rack leans that way. Derek Rose has the Basel micro modal jersey set, Zimmerli a jersey tee and a striped camp-collar set, and CDLP a lyocell camp-collar shirt. For your feet, the Brunello Cucinelli ribbed wool and cashmere-blend socks, the Mr P. cashmere and silk-blend pair and the Falke N9 Finest three-pack cover different moods. Caps come from Brunello Cucinelli, Loro Piana and LOEWE, and the Loro Piana ribbed cashmere scarf is the one soft thing I would carry outside. What I would skip: the TOM FORD polka-dot silk tie, which belongs to a different evening than this one.
