What to do about the post-holiday bracketing spike
Expect bracketing to spike in January as gift recipients exchange sizes. Separate one-time gift exchanges from habitual bracketing behavior before you tighten policy, or you will punish new customers for a seasonal pattern.
Gift-season bracketing looks different from the habitual kind. The January spike is mostly first-time customers making a single exchange, not serial bracketers working the system. The order history tells the story: one bracketed order from a new customer in early January is a gift exchange. The same pattern repeated across October, November, and December is behavior.
Do not change return policy in January. Enforcement changes made during the spike land on the wrong people, because the population bracketing right now is not your normal bracketing population. Use January data to segment gift-driven brackets from habitual ones, then act on the habitual segment in February when the noise clears.
Fix the fit content that gift buyers see. Someone exchanging a gifted sweater lands on your product page with no brand familiarity, and size guidance written for loyal customers fails them. Clear model measurements, honest fit notes, and a simple size finder earn their keep in January. Every gift exchange you convert into a kept item is a customer acquired at zero acquisition cost.
One more thing worth doing with the January data: look at which products drove the most gift bracketing. If the same three styles show up in every exchange, the fix is not policy at all. It is a fit note, a size chart correction, or a model photo that actually represents the range of bodies buying the product. Policy handles behavior. Product content handles confusion. January tells you which one you are dealing with, but only if you look at the product level instead of just the customer level.
