Using a Well-Fitting Garment as a Reference
Prepare a useful measurement reference by keeping the garment, units and measuring method consistent.
Set up carefully
Lay a suitable garment smoothly on a flat surface without stretching it. Record the units and identify whether each value is flat or a full circumference. Photograph the measurement points if you need the seller to understand exactly how you measured.
Compare similar constructions
A reference from a different garment type may not predict the same fit. Explain the reference style and what you like or dislike about it. Ask for the selected product’s measuring method so the comparison does not mix different starting points or size systems.
