French Designer Ready-to-Wear / designer trousers

Patou Lock flared tailored trousers in Mercury wool in Grey, from our designer trousers edit

The Patou Lock flared tailored trousers in Mercury wool is an authentic Patou piece in Grey from the Fall/Winter 2025 collection, made in 100% virgin wool; Lining: 100% viscose, and one of our designer trousers. Available now at Coveti, a curated luxury-fashion retailer with guaranteed authenticity and worldwide shipping. Patou is the Paris house Jean Patou founded in 1914 and LVMH relaunched in 2018, and its ready-to-wear reads as couture thinking at a wearable scale: the JP monogram carried over from the founder’s sportswear line, the volume blouse, the bloomer skirt, the tailored wool jacket, and Les Essentiels, the permanent range the house keeps in production from year to year.

In Mercury, the lock flared tailored trousers are made from 100% virgin wool. Long flared leg. Silver-tone lock fastening and concealed zip at the front. Belt loops.

The Patou Wardrobe

  • Les Essentiels: the permanent range. The house keeps it in production from year to
    year rather than replacing it each season, so the logo t-shirts, the tank tops, the jersey and the
    Iconic trousers stay buyable across collections.
  • La Patou Blouse: the house blouse. A high-volume body with a drawstring collar and
    long grosgrain ties that knot at the neck and drop off the shoulder, cut in organic
    cotton poplin and recycled faille.
  • Tailoring: collarless and double-breasted jackets with JP-engraved gold-tone
    buttons, cut in RWS virgin wool twill with a touch of elastane, and the Iconic trouser that runs
    straight with signature darts at the back.
  • The bloomer: the gathered mini skirt and mini dress the house returns to every
    season, worked in recycled faille and organic cotton.
  • The JP monogram: Jean Patou marked his 1920s bathrobes and swimwear with his
    initials for Deauville, Cannes and Biarritz. The same two letters run through the jersey, the
    jacquard knits and the denim today.

How to Wear the Lock flared tailored trousers in Mercury wool

  • The Patou proportion: the house pairs volume up top with a clean line below, so a
    blouse with real sleeve volume sits over a straight trouser rather than a full skirt.
  • Day into evening: a wool jacket over the matching trouser reads as a suit for the
    office, then opens over a t-shirt and denim at the weekend.
  • Colour: Grey is an easy base in the Patou palette, which runs from black and
    ivory through the house tartans and the Rodeo Blue denim.
  • The finish: keep the jewellery to one piece and let the cut do the work.

Perfect Occasions for the Lock flared tailored trousers in Mercury wool

  • The working week, where the wool tailoring carries a full day
  • Weekend dressing, with the jersey, the denim and Les Essentiels
  • Resort travel and warm-weather city days, with the summer capsule and the bloomer skirts
  • Day-to-night dressing in cities including London, Sydney, New York and Dubai, where Coveti customers wear Patou

About Patou

Patou is a French luxury house founded
in Paris in 1914 by Jean Patou, the couturier who put women in dresses without corsets, shortened the
skirt, built a sports line meant to be worn in town, and dressed the tennis champion Suzanne Lenglen.
Between 1919 and 1924 the house’s revenue grew thirtyfold, and in 1930 Patou created Joy, sold as the
most expensive perfume in the world. After the founder’s death in 1936 the maison passed through some
of the great names in fashion, Marc Bohan, Karl Lagerfeld, Michel Goma, Jean Paul Gaultier, Angelo
Tarlazzi and Christian Lacroix, before the couture activity stopped in 1987.

LVMH acquired the fashion business in 2018, dropped the first name, and relaunched the maison simply as
Patou. Guillaume Henry led the artistic direction from that relaunch until February 2026, rebuilding
the house around a light, joyful ready-to-wear line rather than couture. The atelier sits on the
Île de la Cité in Paris, a few steps from Notre-Dame. Patou states that more than 60% of
its ready-to-wear is made with organic cotton, recycled fibres and recycled wool, that its jersey is
100% organic cotton made in Portugal, that it uses no fur and makes its handbags only from upcycled
leather, and that the collection is mainly produced in Europe. Every piece carries a QR code that
traces the workshop that made it.

“The Patou Lock flared tailored trousers in Mercury wool in Grey is the kind of piece we recommend to women who want French dressing without the formality. The 100% virgin wool; Lining: 100% viscose is the reason it lasts, and the cut is quiet enough to wear on repeat.”

Gemma Deeks, Fashion Editor at Coveti

Frequently Asked Questions

Is the Patou Lock flared tailored trousers in Mercury wool authentic?

Yes. Every Patou piece sold by Coveti is 100% authentic and authenticity-verified before dispatch, including the Lock flared tailored trousers in Mercury wool in Grey.

What size is the Patou Lock flared tailored trousers in Mercury wool?

The leg flares from the knee. Patou cuts to French sizing, so FR 34 to FR 44 shows here as UK 6 to UK 16 on the house conversion. UK sizing runs 4 UK, 6 UK, 8 UK, 10 UK, 12 UK, 14 UK, 16 UK, 18 UK. Patou cuts to French sizing, so the house FR 34 is a UK 6 and FR 44 a UK 16 on its own published conversion. If you are between sizes, the house publishes no blanket instruction, so order your usual size and read the fit note above.

What is Patou known for?

Patou is the Paris fashion house Jean Patou founded in 1914, known first for freeing women from the corset, for the JP monogram he put on 1920s sportswear, and for the perfume Joy, launched in 1930 and sold as the most expensive perfume in the world. LVMH relaunched it in 2018 as a ready-to-wear house, and today it is known for La Patou Blouse, the bloomer skirt, the Iconic trouser, Le Patou Bag and Les Essentiels, its permanent range. The name is shared with several unrelated things, including the Pyrenean livestock guardian dog and a sneaker colourway, so to be precise: this is the French luxury maison at 8 quai du Marché Neuf, Paris, listed on Wikidata as Q3173864.

Who owns Patou, and is it a French brand?

Patou is French, founded and still based in Paris, and it is owned by LVMH. The group announced a strategic agreement with Designer Parfums in September 2018 and took a majority stake in the clothing division, then dropped the first name so the maison trades as Patou rather than Jean Patou. Designer Parfums retains the fragrance business, which is why the perfume Joy and the fashion collections sit with different owners. Coveti stocks the ready-to-wear, bags, jewellery and accessories, not the fragrance.

Is Patou a luxury brand?

Yes. Patou is an LVMH maison with its own atelier in central Paris, and it was a couture house from 1914 until 1987. It sits in what the trade calls accessible luxury rather than at Dior and Louis Vuitton money: at source a logo t-shirt runs about 190 euros, La Patou Blouse about 490 to 590 euros, a wool jacket about 990 euros and Le Patou Bag about 1,100 euros, which places it alongside Jacquemus and above the Paris contemporary labels.

Who designs Patou?

Guillaume Henry was artistic director from the LVMH relaunch in 2018, showing his first collection in September 2019, and the house parted ways with him in February 2026 after the Autumn/Winter 2026 show. Patou has not named a successor, so the collections on sale here are from his tenure. Before Patou he led Carven and Nina Ricci.

What is the Patou Lock flared tailored trousers in Mercury wool made from?

The Lock flared tailored trousers in Mercury wool is made from 100% virgin wool; Lining: 100% viscose, in Romania. Patou works in organic cotton, recycled faille, RWS virgin wool, wool and cashmere, calf leather, raffia and plated brass.

Is Patou a sustainable brand?

Patou publishes its own figures. The house states that more than 60% of the ready-to-wear is made with organic cotton, recycled fibres and recycled wool, that its t-shirts, sweatshirts and polos are 100% organic cotton made in Portugal, that 90% of the samples it develops go into production, that it uses no fur, and that the collection is mainly made in Europe with jewellery made in Bali and some pieces in Madagascar. Every product carries a QR code tracing the workshop that made it.

How should I care for the Lock flared tailored trousers in Mercury wool?
