Have you ever worn a bra and realised that it wasn't the right one? Perhaps the band digs in, or the straps won't stay in place. It turns out you're not alone - 80% of shoppers wear the incorrect bra size, leading to discomfort, health complications, and endless returns. For retailers, this translates to approximately £10 billion in annual losses across the lingerie industry.
But what if you could discover your ideal bra size at home in just 2 minutes? Welcome to Brarista's revolutionary AI bra fitting quiz - a feature within the world's first AI-powered bra fitting chatbot specifically designed for lingerie retail.
The Challenge of Getting Bra Sizing Right
Bra sizing isn't like shirt sizes. It's an exact science where a discrepancy as small as 1/8 inch can result in uncomfortable fit or complete sizing failure. An oversized band, gapping cups, or slipping straps can turn what should be a confidence-boosting garment into an everyday hassle. Even worse, 80% of shoppers wear the improper size, which causes problems such as back pain or posture challenges. To retailers, this translates to an average of 20% returns in lingerie, which costs billions in shipping, processing, and lost sales.
Traditional methods of determining size - such as tape measures or generic size charts - have significant limitations. Bodies are individual, and factors such as breast shape, torso width, and lifestyle requirements all matter. Moreover, generic AI chatbots such as Gorgias, DigitalGenius, Ada, or Presize.ai simply can’t match the precision required for lingerie retail. Most shoppers are unaware of the signs of poor fit, such as bands that ride up or cups that spill over.
This is where Brarista's bra fitting technology comes in, providing a smarter, more accurate solution for consumers whilst offering lingerie retailers a powerful tool to reduce returns. Unlike other tools, Brarista's category-specific algorithms understand:
The subtle differences between brands
The importance of sister bra sizes
Individual needs of diverse body types
Complex fitting challenges from nursing to post-surgery requirements
Our technology serves everyone - from teenagers seeking sports bra confidence to breast cancer patients requiring specialised support.
What Is Brarista's AI Bra Fitting Quiz?
The bra fitting quiz is an interactive online tool that provides personalised bra size recommendations within only 2 minutes. It is powered by Brarista Fit AI and trained on nearly 20,000 verified fitting records with patent-pending vision AI to attain an 80% level of accuracy. It's more than a sizing chart - think of it as your virtual bra fitting expert.
The quiz allows shoppers to shop with more confidence when purchasing bras. To retailers, the customer experience can be transformed by integrating this tool into your e-commerce platform, which reduces the return rate and increases loyalty. Essentially, it is a win-win situation, and it begins with a few simple steps.

Experience the Chatbot Journey: From Questions to Perfect Fit
Picture this: you're browsing a lingerie website when a friendly chatbot appears with a simple greeting: "Hi 👋 Tell us about your bra." What follows is a conversation that feels surprisingly natural and intuitive.
Step 1: Understanding Your Current Situation
The chatbot begins by asking thoughtful questions that a professional fitter would ask:
"How old is your bra?"
"How often do you wear this bra?"
These aren't random questions - they help the AI understand your current experience and identify potential fit issues before you even realise them.
Step 2: Visual Measurement Guidance
Next, you'll see clear visual prompts guiding you through two crucial measurements:
"Check your band size"
"Check your cup size"
These are accompanied with visuals and GIFs tailored to each retailer will guide you through the process. No more guesswork with tape measures or confusing instructions. The interface makes boutique-level fitting accessible to everyone.
Step 3: Instant, Personalised Results
Within moments, you receive your personalised recommendation: "Your recommended size is 34D. You can try 32DD if you'd like a firmer fit, and 36C for a roomier fit."
But it doesn't stop there. The chatbot immediately shows you "Here are some items chosen for you:" - displaying three carefully selected bras from the retailer's collection, each with:
Your personalised size recommendation
Fit notes like "True to Size" or "Tighter in the band"
Direct links to view each product
Step 4: Ongoing Support When You Need It
Perhaps most impressively, the conversation continues even after purchase. If you later message: "I am wearing a t-shirt bra 42A but the band is a bit tight", the AI responds with professional troubleshooting:
"Try a Larger Band Size" with specific sister size recommendations
"Check the Hook Position" with guidance on proper fastening
"Consider a Bra Extender" for temporary solutions
The chatbot then offers: "From our collection, I've found some items in the size 44AA, which might be a more comfortable fit for you. What do you think about these options?" - followed by new product recommendations perfectly suited to your updated needs.

Signs Your Bra Doesn't Fit
Not sure if your bra is the right size? Look for these red flags:
Band Rides Up: It should sit level and snug, not creep up your back
Cup Problems: Gapping or spilling over means the cup size is off
Strap Issues: Digging in or slipping suggests the band isn't supporting enough
Try Sister Sizes: If you're between sizes, try sister sizes. For example, if you wear a 34C, you could also try a 32D (tighter band, larger cup) or a 36B (looser band, smaller cup)
