The vocabulary
The chip rows are not free text. They are a vocabulary the studio reasons about.
Every option belongs to an axis. The cuff axis holds barrel, rolled, ribbed, elasticated and no cuff — five answers to one question — and axes are what the studio understands.
Hover to see what a term means
A chip with a dotted underline carries a definition. Those exist because a model could not reliably tell a welt pocket from an inseam one, and the same sentence is sent to the model and shown to you. Where a name is unambiguous — v-neck, boat neck — there is no definition, because one for every term would bury the few that matter.
A chip click is remembered as a requirement, not just text in a box. The choice travels with the design and reaches the tech pack, which states it rather than guessing it from the picture.
That is the difference between a pack that says “elasticated cuff” and a pack whose two diagrams disagree about what they can see.
