Finding stretch poplin
Stretch is a constraint on poplin, not a separate fibre. Confirm it on the fabric page after you filter.

Marketplace check
Poplin is filed here as plain weave. One reason to open it is clean surface for shirts and uniforms. One reason to sample is crispness vs softness is a finish decision.
Judge stretch together with construction. Poor recovery creates bagging. Too much stretch can distort tailored shapes.
What not to assume
A stretch filter does not certify the cloth. shirts, blouses, uniforms are common places buyers test poplin, and some of those garments will reject this attribute.
Questions
