The Ultimate Conversion Booster for Fashion Brands
For most fashion brands, sizing & fit feels like a roadblock:
When size becomes a guessing game for the customer, it:
- It causes returns
- It creates doubt at checkout
- It quietly kills conversions
Let’s face it – finding the right size and fit online is never easy.
Customers rarely know:
- product measurements;
- how stretchy the fabric is;
- what the fit of the garment is meant to be
(tight, fitted, loose); - what design and wearing “ease” is built in the product;
- that each brand has their own size designations depending on target market, and they are not “M” for every fashion brand…
But what if you flipped the narrative?
What if accurate sizing became your biggest sales driver?
📊 According to The Business of Fashion,
“What matters most to customers is confidence in size and fit – not gimmicks.
Over 40% of EU5 shoppers say personalized size recommendations are one of the top factors influencing their decision to buy online.”
Shoppers aren’t just browsing.
They’re looking for certainty:
- Will this fit me?
- Will it flatter my body shape?
- Which size should I pick?
- Will I have to return it?
What if instead of chasing customers with discounts…
…you kept them with confidence?
✔ Confidence they picked the right size
✔ Confidence they won’t need to return
✔ Confidence your brand understands their body
That’s not a problem to fix.
👉 That’s a growth lever waiting to be pulled.
That’s exactly what SizeSense.ai – size recommender now equipped with virtual try-on delivers.

SizeSense.ai Size Recommender Features
Size Recommendation
SizeSense’s key innovation is its proprietary size recommendation algorithm, developed from real-world expertise in made-to-measure fashion, patternmaking, and garment production.
Unlike other tools, SizeSense achieves 94% accuracy by making a 1:1 alignment between customer body measurements and each garment’s actual measurements -factoring in body shape, fit preferences, clothing design, and fabric elasticity.
Our technology sets us apart by uniquely calculating fabric elasticity’s impact on fit, ensuring highly precise recommendations that reduce returns and boost conversions for fashion brands.
AI Styling Assistant
- Conversational interface – customers can ask anything
- Measurements from body-scan or manually from user
- Size-calculation
- Virtual-try-on
- Product recommendation (personalised style assistant) tailored to the customer’s body measurements and shape, using the brand’s inventory
- Up-sale and cross-sale
- Location/page based reminder prompts – for example check size at checkout, etc.
Body Scan
Customers are able to estimate their body measurements directly from an image. They can review, adjust, and save their measurements from their first interaction – making every future purchase faster and more personal.
If the user provides measurements manually, we can calculate size using only the chest, waist, hips.
But if customers upload a photo of themselves, they’ll receive a size recommendation based on their chest, waist, and hip circumference, as well as arm length, inseam, and shoulder width and height.
Virtual Try-On
Yes, we’re integrating virtual try-on – but with a twist. Customers will only be able to try products that fit their measurements. Because true realism starts with the right fit.
Upsells & Cross-sells
No more random recommendations. Customers will only see products we’ve already verified will fit them – boosting satisfaction and reducing returns.
