Start with the intended closed-front fit
State whether the cardigan is intended to be worn fully buttoned, partly open or as an open layer. For a buttoned style, identify the intended underlayer and the fit reference for each selected size. Check finished samples standing and sitting, with a small set of agreed movements such as reaching forward. Record the size worn, fit-reference measurements, layer and buttoning position. A flat chest measurement alone does not approve the worn front. Do not stretch a sample onto an unsuitable fit reference and then treat the result as a production defect. Include a larger size and any size where button count or placement changes; agree the sample coverage rather than assuming one base size represents the whole order.
