SMS/Fit rounds and size sets
What this service is
SMS/Fit rounds and size sets (where required) is a fashion manufacturing development service that controls fit approvals and confirms sizing before bulk production. We manage SMS samples, structured fit rounds, and size sets so measurements, tolerances, grading, and construction stay aligned to your tech pack and approved standard. This reduces sampling delays, prevents fit drift across sizes, and improves sizing consistency for e-commerce brands by locking fit before PPS and bulk production.
Where brands use it
New collection development, first production runs, supplier changes, size range expansion, uniforms/teamwear programs, and categories where sizing consistency drives returns (denim, tailoring, knitwear, activewear, childrenswear, and extended sizing). Size sets are especially valuable when grading is new, when fit blocks are being established, or when stretch fabrics and complex construction increase size-to-size risk.
What you receive
A managed fit approval pathway: fit round scheduling and review, a consolidated fit and measurement comment log, measurement reconciliation against the tech pack (POMs, tolerances, measurement method consistency), grading and balance checks across sizes, and a documented approvals trail. Where size sets are required, we confirm size-to-size consistency (proportions, key measurements, construction execution) and lock the approved fit standard so PPS and bulk production run from one controlled reference.
How delivery works
We confirm fit intent, base size, and size range first, then align the sampling plan (SMS, fit rounds, and size set requirements) to your critical path. Each fit round is reviewed against the latest spec, comments are consolidated into a single factory-facing update, and changes are version controlled in the tech pack. For size sets, we review multiple sizes side-by-side to validate grade rules, balance, and tolerance behaviour, then lock final approved measurements and construction standards before PPS.
What we need from you
Your tech pack and measurement spec (or inputs to build them), fit intent (slim/regular/oversized), target customer and market, size range, any existing fit blocks or size charts, fabric details (woven/knit, stretch and recovery), and your approval chain (who signs off fit and sizing). If you have prior samples or return/fit feedback, we use it to guide decisions and reduce future returns.
FAQ
What is an SMS sample? A salesman sample used for internal review, selling, and pre-production alignment. It often sits between early protos and PPS depending on your process.
What is a fit round? A structured sampling iteration where fit, measurements, and construction are reviewed and updated until the style meets the approved standard.
What is a size set? A set of samples in multiple sizes to confirm grading, proportions, and fit consistency across the full size range before bulk production.
Do we always need a size set? Not always. It’s most valuable for new blocks, new grading, new factories, stretch fabrics, or complex categories where size-to-size consistency is a common risk.
How does this reduce returns? By validating grade rules and fit consistency before bulk, customers experience predictable sizing across sizes and reorders.
