The La DoubleJ Aesthetic: Elevating Your Frequency
The Magic of Archival Prints
At the very heart of the La DoubleJ universe is its unparalleled relationship with color and pattern. Founder J.J. Martin originally launched the brand by sourcing and repurposing vintage patterns from the archives of Mantero, a legendary silk manufacturer in Lake Como, Italy. These historic, kaleidoscopic prints are re-colored and applied to modern, sweeping designer dresses and fluid separates, creating a look that is simultaneously retro and sharply contemporary.
100% Made in Italy
La DoubleJ is fiercely protective of Italian craftsmanship. In an industry dominated by offshore production, the brand remains steadfastly committed to a “100% Made in Italy” supply chain. From the heavy silk twills and crisp cotton poplins woven in Como to the expert tailoring executed by artisans in Milan, every luxury ready-to-wear garment is a love letter to Italian heritage. When you wear La DoubleJ, you are enveloped in the highest echelons of European quality.

La DoubleJ sizing at a glance
La DoubleJ uses three sizing systems depending on the piece, and it runs true to size in all of them. Lettered sizing covers the swing dresses, kaftans, silk tops and jersey. Italian numeric sizing covers the tailored and structured styles. Denim is sold in inch waists. Coveti shows the numeric styles on the UK ladder, so there is nothing to convert.
| Letter | UK | IT | FR | US |

La DoubleJ questions, answered
Is it La DoubleJ or La Double J? The house styles its name as one word, La DoubleJ. It is commonly written La Double J, and both refer to the same Milanese label founded by J.J. Martin.
Does La DoubleJ run true to size? Yes. The house publishes no sizing correction on its ready-to-wear. The swing shapes are cut slim through the shoulder and generous through the hip, so take your usual size.
What is La DoubleJ known for? Bold vintage-inspired Italian prints, re-coloured from archival textiles and applied to easy modern shapes. The swing dress is the signature.
Where is La DoubleJ made? In Italy, working with historic Milanese and Lake Como textile mills, including the Mantero silk archive that J.J. Martin drew on when she founded the house in 2015.
What is a Placee print? A placed print, positioned individually for each size so the motif lands where it should on the finished garment. It is why La DoubleJ prints photograph slightly differently across the size range.
How should I care for a La DoubleJ silk dress? Dry clean it, store it on a padded hanger and keep it out of direct sunlight. Jersey and knit styles are more forgiving.
