**Title: The Fascinating Origins of “Se Mettre sur son 31″**

**Introduction:**
The phrase “se mettre sur son 31” is a common French expression that means to dress up elegantly. But have you ever wondered where this intriguing phrase comes from? Let’s delve into its history and uncover the fascinating origins behind it.

**The Luxurious Fabric “Trentain”:**
The most widely accepted origin of this expression dates back to the Middle Ages. “Trentain” was a luxurious fabric renowned for its quality and expense. Woven with 30 times 100 threads, it was a symbol of opulence. Over time, the term “trentain” evolved into “31,” giving birth to the expression “se mettre sur son 31.” This transformation signifies the act of adorning oneself in the finest attire, much like the exclusive fabric.

**Other Theories:**
While the “trentain” fabric is the primary source, there are other theories worth exploring:
– **Jesuit Tradition:** Some historians suggest a link to a Jesuit feast on July 31st, where novices received new robes, symbolizing renewal and celebration.
– **Military Context:** In a military setting, particularly in Prussia, soldiers would prepare for inspections on the 31st of the month. This practice, known as “tenue 31,” involved wearing their finest uniforms, adding another layer to the expression’s possible origins.

**Clarification: Not Just for New Year’s Eve:**
Interestingly, despite the number 31, the phrase isn’t directly tied to December 31st or New Year’s Eve. Its roots lie deeper in history, emphasizing the act of dressing up rather than a specific holiday.

**Conclusion:**
“Se mettre sur son 31” has evolved from a reference to a luxurious fabric to a broader expression of dressing elegantly for special occasions. Whether it’s the “trentain” fabric, a Jesuit tradition, or military inspections, the essence remains the same: to present oneself in the best possible light. This expression’s journey through history is a testament to the enduring significance of appearance and celebration in our culture.
