LE CHEMISEUR® demonstrates how AI can help create a new, more personalized and eco-friendly luxury.

The brand has achieved +45% growth in 2025, and is currently launching the concept in Germany and Switzerland.

Key facts

LE CHEMISEUR® is a French online bespoke shirt specialist, founded in 2014 by Jan Schütte, a German engineer based in Paris.

LE CHEMISEUR® has developed a proprietary AI that calculates customers' Fit simply from weight, height, age.

To build customer loyalty, the brand has patented the Fit Key principle, a personal code inscribed on each product that makes reordering simple and fun.

LE CHEMISEUR® has over 50,000 customers and has been B Corp certified since 2024.

1. AI that creates value for customers, the environment and society

The AI developed by LE CHEMISEUR® facilitates online ordering. Its implementation has improved the conversion rate by +30% compared to measuring with a measuring tape. The customer simply answers a few questions (Weight, Size, Age, Morphology and Usage) and the site calculates the ideal Fit based on data from 50,000 similar customers.
The returns rate is just 5% (compared with 20-30% in typical fashion e-commerce), thanks to the precision of the AI, and strong customer loyalty (almost no returns on re-purchase).
The AI improves regularly thanks to machine learning. Every touch-up (1-2 cm) improves the learning process.
Zero stock and overall a 43% reduction in CO₂ emissions per shirt, compared to the average e-commerce mode.

Why it's innovative: Unlike brands that test bet everything on generalist LLMs, LE CHEMISEUR® has developed a simple, frugal but specialized AI in-house, trained on internal, secure data. It delivers real value today.

It's an example of the precision economy, using technology to deliver high-quality, customized services while reducing financial and ecological waste.

2. High loyalty, no promotions

LE CHEMISEUR® achieves an exceptional re-purchase rate of 63% within 6 months. With :

Single, fair price: Shirts start at €99 and go up to €195 (premium).
No sales: Unlike almost all competitors in men's shirts.
Loyalty through experience: The Fit Key (unique 5-character code) enables one-click recommendations based on a previous shirt.

The absence of promotions is consistent with the brand's ecological commitment ("we don't push consumption") and with the constraints of industrial organization: no stock, no unsold items to sell off, and the need for the workshop to have a stable production rhythm.

3. A new "quiet luxury": fashion as a service

Classic luxury brands show beautiful models as if on a pedestal. We buy products to look like them.

Fits are adapted to each customer (including atypical morphologies).
The customer's name printed instead of the label.
No logos visible from the outside, but high-quality fabrics and comfortable, elegant fits.

4. A redesigned, B Corp-certified production system

LE CHEMISEUR® is not a "green-washing" brand that has chosen a few organic fabrics. Over the past 10 years, it has completely rebuilt a more virtuous production and marketing system.

B Corp certification obtained: Score of 95.3/200 (required threshold: 80).

43% reduction in CO₂ emissions compared with the e-commerce fashion average.

Concrete figures:

Zero overproduction versus 20% in fashion (source McKinsey 2020). Each shirt is ordered before being manufactured.
5% returns (vs. 20-30% in fashion e-commerce) thanks to the Fit Key system.
European fabrics and optimized supply chain: manufacturing in Tunisia and Portugal, plane-free delivery, zero plastic kraft packaging.

5. A French brand created by a German, now launching in DACH
