Weight definitely matters, but you also have to consider weave tightness, fabric stiffness and how the cut drapes. If you want a piece that moves just right, start by measuring the weight per yard, then test how it behaves under a small weight—like a hand—before scaling up. That way you’ll catch any quirks before you commit to the whole garment.

Sounds solid. Just remember to keep the testing consistent—same hand, same grip, same angle—so you can compare changes accurately. Once you’ve nailed the weave and cut, a quick run‑on‑a‑model will seal the deal. Good luck.
