Using a size finder quiz, this Shark Tank-backed brand helped customers purchase the right apparel and avoided 23.4K coat returns in one year.

Buckle Me Baby Coats invented children's coats designed for car seat safety. Afraid of the dangers that regular children winter coats create in a car crash, founder Dahlia Rizk set out to create an easier, safer alternative.
If you are a true fan of Shark Tank, Dahlia's story should sound familiar. She secured a deal with Daymond John during episode seven of season 12, and set her sights on conquering her next major challenge: reducing exchanges.

"The American Academy of Pediatrics and the NHTSA both recommend taking traditional coats off in the car seat. The coat is going to add padding underneath the harness which creates space, and that space is dangerous for a child. In a crash it can lead to critical brain, neck and spine injuries. But most busy parents find it really hard to take the coat off every trip, so I designed a coat that can stay on safely and be used with the harness correctly all in one easy step."
After her big Shark Tank win, Dahlia's next step for Buckle Me Baby Coats was clear: reduce exchanges. At the time she discovered Octane AI, she had a few challenges—including the seasonality of her winter coats business—but the biggest issue was her exceptionally high exchange rates.
"My return and exchange rate was out of this world—just very, very high at the time I approached Octane AI. I knew there were several problems contributing to that. The first one ties into how many times we redid the coat sizes and the inconsistency between all the different lines of coats. I'm not a designer, I don't have a production background. So these are things I learned along the way that influenced my return rate. The second was that people didn't really read the size charts I had on the site."
Buckle Me Baby Coats' quiz helps customers match the exact size and level of warmth that they need for their children. Instead of a static size chart that site visitors tend to overlook during the shopping process, now Buckle Me Baby Coats has an interactive quiz that teaches shoppers how to select the right size.
The first challenge—inconsistency in sizes between coat lines—was fixed by standardizing sizes. Dahlia told us: "I don't know that I would have thought of making the sizes consistent between lines if we didn't have the quiz." During the quiz building process, Dahlia realized it would be much easier to make all coats consistent across styles and body size.
With sizing standardized, the next step was addressing size education. The quiz gives customers an interactive tool to help them understand what size they need— instead of hoping they'll read a static size chart, the quiz actively guides them to the right choice.
The quiz asks about the child's age, height, weight, and typical clothing size to determine the perfect coat fit.
Questions about climate and usage help match customers to the right level of warmth for their needs.
Interactive visuals help parents understand sizing better than traditional text-based size charts.
Each customer receives a tailored recommendation based on their specific answers, not generic suggestions.
