What Is Sizing Like at Les Tien?

Les Tien runs generously oversized and is cut to a unisex, men’s-leaning block — so as a rule, most women should size down at least one size for anything other than a deliberately slouchy, borrowed-from-the-boyfriend look. I learned this the slightly expensive way. I ordered a heavyweight hoodie in my “normal” size, fully expecting that buttery cult fleece to hug me just so, and instead I spent a fortnight looking like I’d shrunk inside a duvet. Beautiful duvet. Wrong size. So before you part with the not-insignificant sum these pieces command, let me save you the reorder.

How Les Tien Actually Fits

Les Tien is the Los Angeles label that turned the humble sweatpant into a status piece — garment-dyed heavyweight cotton, gold grommets, that lived-in fade you can’t fake. It’s been on Hailey Bieber, Gigi Hadid and Billie Eilish, which tells you everything about the aesthetic and nothing useful about your size. Here’s what you actually need to know:

It’s built on a unisex, men’s-influenced block. The cut is intentionally boxy with dropped shoulders, so the proportions read roomy on a typical women’s frame.
The cotton fleece is substantial. This is properly heavy, structured fabric — it holds its shape, barely shrinks, and won’t cling or drape the way a thinner jersey would.
True to size = deliberately slouchy. If you love the oversized, off-duty look, take your usual size and enjoy it.
Size down for anything sharper. Want a hoodie that skims rather than swamps, or joggers that taper neatly at the ankle? Drop a size, sometimes two if you’re petite.
The range runs roughly XXS to XXL depending on the style — but because of the unisex cut, that scale doesn’t map neatly onto how you’d normally read XS or S.

The Cashmere Is a Different Conversation

Les Tien’s hand-knitted Italian cashmere — the lounge pants and hoodies you’ll see at Net-a-Porter and The Outnet — fits even more oversized than the cotton. It’s graded to men’s sizing, so the brand themselves advise women to size down for a less swamping fit. My honest take: on these I’d go down a full size from your cotton choice if you want them to look intentional rather than inherited. The exception is the cashmere track pant, which several retailers list as true to size with a relaxed leg — so if you like a fluid, draping trouser, your normal size is fine there.

My Honest Sizing Advice

Slouchy-and-cosy is your priority? Stay true to size. That’s the look the brand is famous for, and it’s gorgeous.
Want it more flattering and considered? Size down one for cotton, one (or two) for cashmere.
Petite or small-framed? Be brave and size down — the volume can otherwise wear you rather than the other way round.
Buying a matching set? You can mix sizes — many people take the top true to size for that boxy crop and size the bottoms down for a cleaner line.

Where to Shop for the Les Tien Look

Les Tien is an investment, and not everyone wants to spend three figures on sweats — entirely fair. Here’s where I’d send clients across every budget for that same elevated-loungewear energy.

High Street

The White Company — the closest high-street match for that quiet-luxury lounge feel, with genuinely lovely cashmere and brushed-cotton joggers.
Hush — the UK’s loungewear specialist; their joggers and oversized sweats nail the off-duty silhouette for a fraction of the price.
Uniqlo — unbeatable on affordable cashmere jumpers and weighty sweat sets; the place to start if you’re testing the look.
COS — minimalist, architectural basics with that same pared-back, considered cut.
Sweaty Betty — premium joggers and loungewear with a polished finish that wears far above its price.
Mint Velvet — soft, tonal knits and relaxed separates for the grown-up version of comfy.
Massimo Dutti — elevated, slightly continental loungewear and knitwear when you want refinement without the designer ticket.

Premium

Brora — the Scottish cashmere house; if it’s the Les Tien knit you covet, this is where to spend with confidence.
Toast — beautifully relaxed, artisanal basics with that lived-in, undone quality Les Tien fans adore.
Theory — clean, modern essentials in lovely fabrications for elevated everyday layering.

Luxury & Designer

The Row — the gold standard for whisper-quiet luxury loungewear and impeccable cut.
Extreme Cashmere — Amsterdam’s one-size cashmere cult, slouchy and addictive in the same vein.
Khaite — for when you want your soft pieces with a sharper, fashion-forward edge.

Two Independents Worth Knowing

Donni — a small LA label making dreamy, tonal sweats and knit sets with a softer, more feminine drape than Les Tien.
Lunya — an independent luxury sleep-and-lounge brand whose washable cashmere and considered cuts feel quietly indulgent.
