Buying local is great in theory, but it usually falls apart at the cash register. We all want to support home-grown manufacturing until we see a €40 price tag on a single pair of briefs. That's the exact wall French underwear manufacturer Le Slip Français ran into after fifteen years of waving the patriotic blue, white, and red flag.
Now, the brand is doing something radically different to survive.
On July 14, 2026—Bastille Day, naturally—Le Slip Français officially launched its initial public offering on the Euronext Growth Paris market. It’s not just a cash grab; it’s a high-stakes test of whether local, sustainable apparel can survive in an era dominated by ultra-fast fashion giants like Shein and Temu.
The company hit the public markets with an initial share price of €14.80, aiming to raise €5 million in fresh capital. Here is the real story of how they restructured their entire business model to make this public debut possible.
The Big Pivot: Cutting Prices Without Killing Profits
For years, the biggest knock on Le Slip Français was the price. Paying €40 for a pair of underwear is a luxury most people can't justify, especially during a cost-of-living squeeze.
So, how do you drop your prices to €20 while keeping production entirely in France?
You don't do it by squeezing worker wages. Instead, Le Slip Français completely re-engineered its supply chain. The company integrated its production by acquiring and building out its own manufacturing facilities. By cutting out middlemen and optimizing its manufacturing processes, the brand managed to slash its retail prices by roughly half while remaining profitable.
- The 2025 Financial Reality: The strategy works. In 2025, the brand pulled in €21.1 million in revenue, turning a net profit of around €600,000 to €700,000.
- Debt Reduction: They cut their net debt in half over two years, dropping it from €7.2 million to €3.5 million by the end of 2025.
- The Production Engine: The company's production plant near Paris now pumps out about 4,500 pieces of underwear every single day.
By showing they could run a tight, profitable ship with solid margins, founder Guillaume Gibault and his team built the financial foundation needed to back up their patriotic marketing.
Why Choose Euronext Growth?
For a company targeting a market capitalization of roughly €19 million, a listing on the main Euronext board would be overkill. Euronext Growth Paris is designed specifically for small and mid-sized enterprises (SMEs). It offers less stringent regulatory hurdles and lower listing costs while still giving the brand direct access to both institutional and retail investors.
During its market debut, the stock showed some immediate volatility, briefly slipping below the €14.80 listing price before stabilizing around €15. This kind of initial fluctuation is completely normal for a micro-cap stock, but the listing itself accomplishes a major strategic goal: visibility.
By taking the company public on France's national holiday, Gibault didn't just execute a financial transaction; he ran a brilliant marketing campaign. He invited the brand's 850,000-strong customer base to buy shares through their standard retail investment accounts, turning buyers into literal brand advocates.
The B2B Play to Double Revenue by 2030
The €5 million raised from the IPO isn't just going toward buying more sewing machines. The company has a highly ambitious roadmap to double its revenue by 2030, and the plan relies on a major shift in how they use their factories.
Instead of just manufacturing their own branded underwear, Le Slip Français is transforming its facilities into a shared production platform for other local brands.

Setting up textile factories in Western Europe is incredibly capital-intensive. By opening up their automated, highly efficient production lines to third-party apparel makers, Le Slip Français can keep its factories running at maximum capacity. This B2B play helps offset the seasonal demand dips of their own retail business and significantly improves overall manufacturing margins.
Can Local Manufacturing Actually Beat Fast Fashion?
Let's be realistic. A single French brand selling €20 boxers is not going to put Shein out of business. The scale is completely different.
However, this IPO proves that local manufacturing does not have to be a charitable endeavor funded by government subsidies or wealthy patrons. If you optimize production, integrate your supply chain, and price your products logically, you can build a sustainable, profitable, local business.
The success of Le Slip Français moving forward will depend on two critical things:
- Maintaining Quality at Scale: As daily production volume increases, they cannot afford a drop in product durability, which is their primary selling point over fast fashion.
- Expanding Beyond Underwear: While briefs are their bread and butter, expanding into socks, pajamas, and swimwear will be vital to hitting their 2030 growth targets.
What to Do Next
If you run an e-commerce brand or write about sustainable business, there are a few clear lessons you can take from this IPO:
- Audit your supply chain for hidden costs: Le Slip Français didn't lower prices by cutting corners on fabric; they did it by taking direct control of their factories to eliminate middleman margins.
- Don't rely solely on "eco-friendly" or "local" labels: Consumers care about sustainability, but they care about their wallets more. Your pricing must be realistic.
- Build community before seeking capital: Part of the reason this IPO succeeded is because the brand spent 15 years cultivating a massive, highly loyal audience of nearly a million people who were eager to buy into the company's vision.
