When it comes to formalwear, fit is everything. For The Dessy Group, a leading online destination for bridesmaid dresses and formal occasionwear, helping customers find the right size on the first try isn’t just a nice-to-have, it’s critical to ensuring a confident purchase and a seamless event-day experience.

That’s why Dessy partnered with TrueToForm to integrate our 3D fit prediction widget into their e-commerce experience. The goal: to make sizing easier, reduce returns, and ultimately increase conversions by empowering customers with more personalized fit guidance.

The Results

Since integrating the TrueToForm widget, the results have spoken for themselves:

• 170% lift in conversion rates among users who used the widget compared to those who did not.
• 59% decrease in return rates for shoppers who used the widget to select a size before placing their order.

These metrics highlight the power of personalized fit recommendations, especially in categories like formalwear, where customers often hesitate to purchase without trying on. By giving shoppers greater confidence in their sizing, Dessy was able to significantly improve both the shopping experience and their bottom line.

“The TrueToForm size prediction software gives our customers a way to make more informed sizing decisions, which leads to fewer returns and higher conversion rates. It’s a win-win.” - Alan Dessy, President & CEO of Dessy Group

Why It Works

TrueToForm’s fit prediction widget gives shoppers multiple paths to accurate sizing. Customers can either create a scan using TrueToForm’s cutting-edge 3D body scanning technology, or manually enter their measurements if they already know them. In both cases, the system generates a visual 3D model of the customer’s body dimensions.

From there, shoppers receive real-time feedback on how a specific product fits across key landmarks of the body - like bust, waist, and hips - and where hemlines fall. Customers can toggle between sizes to compare fit, which is especially valuable in the formalwear category where personal style and tailoring plans often influence sizing decisions.

Whether a customer wants a perfectly fitted garment or prefers to size up for alterations, TrueToForm empowers them to make confident, informed choices - reducing uncertainty and increasing satisfaction.

Looking Ahead

Following the success of the initial pilot, Dessy has since evolved the customer experience by directing shoppers to complete a TrueToForm scan upfront and storing those measurements in the customer account, allowing them to power a fit calculator across their entire catalog - continuing to leverage our 3D measurement data to drive size accuracy even beyond the widget entry point.

As TrueToForm continues to partner with forward-thinking brands like Dessy Group, we’re seeing growing demand for solutions that reduce friction in the sizing journey, especially in high-stakes categories like formalwear and special occasion clothing.

We’re proud to support Dessy in delivering a more seamless and confident shopping experience for their customers, and we look forward to helping more brands unlock similar results.
