Put on a familiar jacket or shirt and notice where the loose lengths meet it. A structured shoulder can give soft hair a useful contrast, but a high collar may change the way the ends sit. Tuck one side, move the front and compare the whole area from the head to the chest.
For an evening version, decide whether the hair or the accessory should lead. If you wear long earrings, exposing one ear may keep the combination readable without reducing the fullness you enjoy. A small adjustment can preserve the mood while making the outfit feel more deliberate.
