Create your first made-to-measure fit with AI
At LE CHEMISEUR®, we know that ordering a made-to-measure shirt online for the first time can raise questions.
This guide explains how our AI sizing works, how to create your first Fit Key, and how to reorder easily afterward.
🧑💻 How does the AI that creates your fit work?
LE CHEMISEUR® AI is built on data collected from more than 50,000 customers since 2014.
This data is continuously refined through:
- customer feedback,
- reorder history,
- and the expertise of our Paris tailoring team, developed through thousands of in-person appointments.
Using machine learning, the system improves over time to provide increasingly accurate made-to-measure fits.
Each new order helps refine the quality and consistency of future recommendations.
✅ What if the fit isn’t right?
Your first order is covered by our 100-day Fit Guarantee. If necessary, we will remake your shirt free of charge.
Thanks to the accuracy of our AI and the experience gained from thousands of fittings since 2014, our return rate remains below 5%.
