size type

also called size group

The GRADING/CUT family a garment is graded to — regular, petite, plus, big and tall, maternity, or tall (the Google Merchant size_type). A plus-size 16 and a regular 16 are graded differently, and a petite 8 and a regular 8 are different garments at the same size number, which is why this is a SEPARATE dimension from `size`: it re-grades proportions (sleeve, rise, back-length, panel) across the whole garment, not just the chosen size value. It is an IDENTITY discriminator, not a buyable facet: when a retailer exposes Regular/Petite/Plus/Tall/Maternity, selecting one navigates to a DISTINCT product listing with its own SKUs, size chart, grading block and reviews (ASOS Petite, Nordstrom Plus, Old Navy Tall are separate pages; an on-page Regular/Petite/Plus control is a cross-link between sibling listings, never a single-product buy-box toggle). Grouped in the `identity` concern, so by the derived-axis rule it is NOT axis-eligible — a seller never offers one product across size_types as buy-box versions. Distinct from `gender`+`age_group` (who the garment is FOR — the department), from `fit` (slim/relaxed silhouette and ease within one grading), and from `size`+`size_system` (the chosen size option and its scale). Optional and single: a listing has one size_type, but a plain regular garment commonly omits it (absent defaults to regular).
