Frustrated with online underwear sizing? Discover how Kleep AI and Le Slip Français are solving fit challenges with AI, ensuring a perfect fit and fewer returns.

Revolutionizing Underwear Sizing Fit

For online apparel retailers, the convenience of e-commerce is often overshadowed by the costly and frustrating reality of product returns. This challenge is especially acute in the intimate apparel market, where the smallest deviation in fit can lead to high return rates and customer dissatisfaction and high return rates. Buying underwear online is a difficult experience, where comfort and confidence are at stake, and misjudging the right size leads to a frustrating cycle of return logistics. Together, Le Slip Français and Kleep AI are tackling this with a shared commitment to e-commerce innovation and sustainable responsibility. Shoppers can now benefit from Kleep’s AI-powered sizing tool, ensuring they don't get the size wrong.

Customers simply tap “Find My Size”, answer a bunch of guided questions, and instantly receive a personalized size recommendation based on their individual body shape. This full-body scan technology eliminates guesswork and dramatically improves sizing precision which is essential for undergarments, where a perfect fit matters most.

Celebrating French Excellence

This partnership is deeply rooted in a mutual vision of celebrating and advancing French excellence. Le Slip Français preserves and promotes French fashion heritage through high-quality, locally made garments crafted with care while Kleep AI provides generative AI applications for real-world retail challenges to a brand. Together, we are demonstrating how fashion and AI can intersect for a more personalised and seamless customer experience.

A Shared Vision, Real Results

This partnership is designed to deliver tangible results for both the business and the environment. As seen in other Kleep AI collaborations, the impact is clear, conversion rates have increased up to 20% as customers gain sizing confidence. Return rates have declined by over 18% due to fewer fit-related issues, which in turn reduces the costly and inefficient reverse logistics chain. This boosts profitability and customer satisfaction improves through a seamless experience.
