Specialist bra insert products for uneven breast sizes
17 bespoke sizes tailored to different cup size differences and bra sizes
TOP LINE CHALLENGES
Evenly’s sizing system isn’t built around standard charts. Each bra insert comes in one of 17 bespoke sizes, varying in shape and thickness to support women with different degrees of breast asymmetry.
While this level of precision is innovative and empowering, it created a challenge: how to deliver expert, personalised guidance online that matched the care of in-person advice. Generic sizing tools weren’t designed to handle the complexity of breast asymmetry, making them unsuitable for Evenly’s bespoke 17-size system.
At the same time, Evenly’s customer service team was handling repetitive queries around fit, product details, and exchange processes. A scalable solution was essential.
"This is especially important for us as a brand, since finding the perfect fit is central to our mission. I wanted to ensure that anyone searching for answers could do so easily, quickly, and with confidence – whether that means suggesting different product options if the first doesn’t work, or guiding someone towards the most relevant information."

The solution
This is where Brarista’s conversational AI came in. Together, we co-created a bespoke, stable sizing system for Evenly’s Balance Bot, the first AI fit assistant of its kind to guide women through complex sizing decisions while offering instant, empathetic support to personal questions.
Key features include:
Custom-Built Sizing Engine: A bespoke sizing system is designed exclusively for Evenly’s 17 unique sizes. It applies rules that account for asymmetry and international conversions, ensuring precise and reliable recommendations every time. Unlike conventional tools, this AI is capable of handling the complexity of breast asymmetry, giving women guidance they can trust.
Real-Time Fit & Exchange Guidance: The chatbot goes beyond static advice to support customers in real time. Through troubleshooting previous purchases and recommending size adjustments, Brarista helps minimise returns and converts them into successful exchanges if necessary. The chatbot guides customers step-by-step through these processes, and reduces the burden on service teams while providing shoppers with instant reassurance.
Breast Asymmetry Education: Brarista provides education and reassurance on one of lingerie’s least-discussed topics of breast asymmetry. The chatbot provides accessible, supportive answers, helping women better understand their bodies and feel confident in their choices. Every interaction is designed to reflect Evenly’s values, making the experience feel both professional and personal.
"Overall, it’s been a really valuable collaboration and I believe any lingerie brand would benefit from working with them. They’ve shown a strong understanding of our operating environment and the challenges we face, and they’ve offered valuable insights into improving conversions and customer experience."

The Results
The strategic partnership delivered measurable advances in sizing accuracy, customer guidance, and scalable specialist support:
17 Bespoke Sizes Mapped & Automated: Evenly’s proprietary sizing architecture was fully integrated into Brarista, enabling seamless conversion from standard band-and-cup systems and intuitive guidance for customers new to bespoke sizing. This ensured clarity and confidence across every fit journey, without compromising precision.
20+ Fitting Scenarios Supported: Brarista provided accurate, empathetic support for diverse breast and body journeys, including lumpectomy, mastectomy, asymmetry, puberty, postpartum changes, weight-related fluctuations, and reconstruction. This reflects Evenly’s commitment to offering effective asymmetry solutions across all causes and life stages.
100% Resolution of Sizing-Exchange Queries: Brarista consistently interpreted customer fit feedback and recommended alternative sizes or products where appropriate. This proactive guidance helps reduce size-related returns, avoids trial-and-error purchasing, and strengthens customer confidence throughout their decision-making process.
Together, we translated Evenly’s highly specialist sizing expertise into a scalable, automated experience. Customers can now access personalised support delivered with empathy, accuracy, and professionalism at every stage of their shopping journey.
