The implication for retail is straightforward. Keep assortments tight where fashion cycles fast, keep payments broad and low‑friction, and use social commerce to meet this audience where they already spend time. Blend online convenience with in-store immediacy, and let real customer behavior (not assumptions), drive decisions.
