ChicWish x Prime AI – How AI Size Recommendations Transformed Returns & Sales
ChicWish, a fashion retailer renowned for its vintage-inspired women’s clothing, faced a common challenge in online retail – high return rates due to sizing issues. Like many e-commerce brands, ChicWish struggled with size-related returns, bracketing (ordering multiple sizes and returning those that didn’t fit), and conversion rates (CVR). Additionally, the brand sought deeper insights into customer demand to optimise inventory, reduce stockouts, and improve marketing efficiency.

To tackle these challenges, ChicWish partnered with Prime AI to implement its advanced Clothing Size Finder, a custom-built AI-powered tool that provides precise size recommendations in real time. This solution successfully reduced return rates, minimised bracketing, increased conversion rates, and improved inventory planning, all while enhancing the customer shopping experience and supporting sustainability goals.
The Challenge
Shopping for vintage-inspired fashion online presents unique sizing challenges, particularly for categories like dresses, skirts, and knitwear, where fit precision is crucial. Before implementing Prime AI’s solution, ChicWish encountered several key issues:
- High return rates due to incorrect sizing across various product categories.
- Significant bracketing behaviour, with customers ordering multiple sizes due to uncertainty and returning those that didn’t fit.
- Sizing inconsistencies across product types, leading to confusion and abandoned purchases.
- Missed revenue opportunities due to stockouts, as high-demand products ran out before the brand could adjust production.
- Limited visibility into customer demand by age group makes it difficult to effectively tailor product offerings and marketing campaigns.
ChicWish needed a comprehensive solution that would reduce returns, improve fit confidence, increase conversions, and provide actionable insights into customer demand, without disrupting the shopping experience.
The Solution: Prime AI’s Custom-Built Clothing Size Finder
By integrating Prime AI size recommendation technology, ChicWish provided customers with accurate, real-time size guidance that continuously learns from sales, refunds, and other data sources. The intelligent system:
- Eliminated customer guesswork, ensuring shoppers selected the correct size without relying on complex size charts.
- Reduced bracketing behaviour, leading to fewer multiple-size purchases and returns.
- Accounted for variations across product types, providing accurate recommendations across dresses, tops, skirts, outerwear, and knitwear.
- Enhanced customer confidence, increasing purchase commitment and reducing cart abandonment.

- Enabled real-time inventory adjustments, allowing ChicWish to predict and react to high-demand products before stockouts occurred.

This seamless integration transformed ChicWish’s e-commerce strategy, improving fit accuracy, driving revenue growth, and making inventory management more data-driven.
