the.com/corsetry

means The craft and business of making corsets and similarly structured, figure-shaping undergarments.

from From 'corset,' a diminutive of the Old French 'cors,' meaning body (itself from Latin 'corpus'). So a corset is literally a 'little body' — a second, stiffer torso laced on over the first. The '-ry' suffix, as in 'millinery' or 'cutlery,' turns the object into a trade: the whole art and industry of whalebone, busks, and lacing built up around that one small word for 'body.'
