LOU Extends Its 'Engineered for Fit' Philosophy with Brarista's AI Bra Fitting Technology

Brarista is proud to announce our newest partnership with LOU, the Australian swimwear, intimates and activewear brand built for smaller busts. Founded by Louise Chen, LOU was created on a simple but powerful conviction: that people with smaller busts deserve swimwear and lingerie engineered to look and feel sexy.

Their commitment to fit extends well beyond the product itself. LOU has long invested in helping customers understand their size and shape through detailed fit guides, style education, and a community built around body confidence. This partnership takes that expertise a step further, bringing intelligent fit and style guidance directly into the online shopping experience at the moment it matters most. According to Louise:

"We wanted to eliminate sizing guesswork for our online customers. Since our designs are specifically engineered for smaller busts with a zero-gap fit, precision is everything. We hope Brarista's solution helps us boost buyer confidence in their online purchases and reduce returns."

For Brarista, this collaboration marks two significant firsts: our first swimwear integration, and the live debut of our breast shape quiz. It also deepens a growing area of expertise in small-bust fitting that began with our partnership with Little Women, and continues here across a new product category.

Introducing the Mini Chatbot

One of the most distinctive aspects of this integration is how Brarista sits within the LOU shopping experience. When we first spoke with the LOU team, it was clear they had an existing customer service setup they wanted to keep. So rather than a full site-wide deployment, we introduced our Mini Chatbot: a lightweight solution that embeds directly below the add-to-cart button on specific product pages, acting like a professional fitter standing beside every product.

Unlike our Full Chatbot, which guides shoppers through the entire browsing journey, the Mini Chatbot is built for removing the doubts that stop someone from adding to cart. It answers product-specific questions about fit, fabric, and compatibility, right at the moment a shopper needs clarity most. The result is a tool that improves product page conversion rates without disrupting the broader customer experience LOU has already built.

The breast shape quiz

This partnership also marks the first live deployment of Brarista's breast shape quiz. It builds on our established two-minute bra fitting quiz, going further to assess shoppers based on a wider range of body features: breast spacing, side and top fullness, bottom gap, shoulder slope, and life stage, to pinpoint which products will suit their body best.

For swimwear and lingerie alike, size is only one part of the equation. As LOU puts it, breast shape plays just as big a role in how a bikini fits, feels, and flatters, much like how different body types suit different cuts of jeans or dresses. The quiz democratises the kind of in-person assessment a specialist fitter would offer at a boutique store into a visual, intuitive experience online.

Louise describes it as a standout feature:

"The visual component and level of detail of their size and shape quiz is exceptional. It's high-tech and aligns perfectly with our 'Engineered for Fit' ethos."

Backed by over 4 years of research and co-created with professional lingerie fitters, Brarista has the depth to advise confidently across body types and breast shapes that are too often treated as an afterthought by generic sizing tools.

Together, LOU and Brarista are transforming how customers shop for lingerie online, bringing expert-led guidance to a category where fit matters most.

The collaboration not only empowers shoppers to choose better-fitting bras, but also reduces unnecessary returns. On the partnership as a whole, Louise adds:

"Collaborative and seamless. The team clearly understands the technical nuances of fit for different chest types. They've been proactive in tailoring the quiz logic to our specific silhouettes, making it feel like a genuine partnership rather than just a plug-in."
