Why we built it
Built on shared fit data the whole industry can trust.
Size Passport exists to share fit and sizing data in a way that helps everyone. Poor fit drives returns, waste, and cost. A shared, neutral fit standard, owned by the people it describes, reduces all three.

Questions, answered
What is Size Passport?
Size Passport is a free digital fit profile that tells you what clothing size fits you across brands, online and in store. You create it once, receive a personal QR code, and scan it while shopping to instantly see the right size. It is built by Caprice Bespoke as neutral infrastructure, so your fit works everywhere rather than being locked to one retailer.
How does Size Passport work?
Size Passport works in five steps. Create your Size Passport once. Receive your personal QR code. Scan the code when shopping online or in a store. Instantly see which size fits you for that brand and item. Earn rewards with participating brands. Your fit travels with you, so you never start from scratch again.
Is Size Passport free?
Yes. Size Passport is free for shoppers. Creating your passport, receiving your QR code, and using it to find your size across participating brands costs nothing. The platform is funded by brand partners who benefit from fewer returns and higher conversion, not by charging the people who own their fit data. You can also earn rewards when you shop.
How does Size Passport protect my privacy?
Size Passport is private by design. You own your fit data and decide which brands can see it, and you can revoke that access at any time. Brands receive only the size recommendation they need, not your raw measurements. Nothing is shared without your permission, and your fit profile is never sold.
How does Size Passport use blockchain?
Size Passport uses a secure shared ledger only to guarantee ownership, transparency, portability, and privacy of your fit data. It records that the data is yours and that access happens on your terms, so your fit moves with you across brands without lock-in. There is no cryptocurrency, trading, or speculation. The benefit comes first: a fit profile you truly own.
How do rewards work with Size Passport?
You earn rewards with participating brands every time you shop using your Size Passport. When you scan your QR code at checkout, online or in store, the brand recognizes you and can credit rewards for shopping with the right fit. Because your passport reduces returns and guesswork, brands reward confident purchases. Rewards vary by brand and grow as more partners join.
Does Size Passport reduce returns for brands?
Yes. Size Passport reduces returns by giving every shopper the correct size before they buy. Fit guessing is a leading cause of apparel returns, so accurate, consistent size recommendations lower online return rates and shorten fitting-room cycles in store. For brands, that means higher conversion, higher lifetime value, more productive associates, and lower reverse-logistics cost.
Does Size Passport work online and in store?
Yes. Size Passport works online and in physical stores. The same fit profile and QR code apply everywhere a participating brand operates, so the size that fits you on a website also fits you on the shop floor. You stop re-guessing your size with every brand and channel, and you spend less time in fitting rooms.
How is Size Passport different from a brand's size chart?
Size Passport is neutral and portable, while a brand's size chart or size finder only works for that one brand. You build your fit once and reuse it across every participating brand and channel, instead of re-entering measurements on each site. It translates your fit into the right size for each brand's own sizing system.
Who is behind Size Passport, and why does it exist?
Size Passport is built by Caprice Bespoke, an Italian made-to-measure atelier in Molise, Italy, as neutral fit infrastructure for the whole fashion industry. It exists to share fit and sizing data that benefits shoppers and brands alike, reducing the waste and inefficiency caused by poor fit and returns. The goal is a shared, owner-controlled fit standard.
