A trend can make a style visible and affect customer demands. However, the store must consider when it will receive the products and how long it can propose them. The popularity observed today does not prove that the same question will be present at the time of delivery.
I propose to distinguish real requests in the store and signals from other contexts. Widespread images can generate curiosity without translating into local purchases. The comparison must include the audience of the activity and the compatibility of the style with the assortment already available.
Let's imagine an accessory required during a media event. An order with much later delivery may come when attention has changed. A limited selection or collection of requests could offer more useful information than a broad purchase based only on visibility.
The review observes sales and interest after the products arrive. The trend remains a signal to be interpreted, with a precise calendar. A store makes better use of this signal when connecting it to customers, times, and resources, while keeping the forecast of its duration prudent.
