Locate the strap junction
Mark where the two straps meet relative to the shoulder blades. A high junction can change neck pressure even if the front neckline stays the same.

Decisions for your first sample
Build cup and band together
State whether the design uses lining, removable inserts or neither. Specify relaxed and stretched band measurements; a tight band alone does not define the support level.
Allow space near the underarm
Show where binding should sit when the wearer reaches above shoulder height. Approve the fabric and seam treatment on the movement required by your brief.
What to check on arrival
Have fit reviewers try the intended activity and remove the sample afterwards. Record band roll, strap pressure and armhole rubbing for each size; do not infer support from appearance alone.
