How do Glamour Star rewards work?

Each prize sits behind a point threshold, so your styling score sets how much you collect. Pass a milestone and its prize is yours. The Sparkling Crystals come with the high rank tiers, so a middling look stops short of them.

You can claim each reward only once. Replaying won't pay out a milestone you have already passed, so the only reason to go again is to reach a tier you missed. A perfect score clears the whole list in one go.
