What is bracketing in fashion ecommerce?
The practice of ordering several sizes or colours of the same item online, intending to keep one and return the rest.
In short
Bracketing is when an online shopper buys the same item in multiple sizes or colours, planning to keep the one that fits best and return the others. It is a common habit in fashion ecommerce and a major driver of returns.
How does it work in practice?
A customer unsure of their size orders, for example, a jacket in two or three sizes. After trying them at home, they keep one and send the rest back, often using free returns. Retailers can detect bracketing in order data, where a basket contains the same style in several adjacent sizes. Some also see colour bracketing, where shoppers order variants to compare in daylight.
Why does it matter for fashion businesses?
Each bracketed order creates extra picking, shipping and returns handling, and the extra units are unavailable to other customers until they come back. For brands with tight stock, this can mean lost sales and later markdowns. Bracketing also signals a deeper problem: customers do not trust size information. Solving that trust issue usually improves conversion, return rate and customer satisfaction together. It is also a sustainability topic, because each extra parcel adds transport, packaging and handling.
How is AI changing it?
AI size prediction tools use purchase history, return data and garment measurements to recommend the most likely size and to communicate how a style fits. Retailers can trigger personalised fit advice when a basket shows bracketing. Analytics identify styles where bracketing is unusually common, which often points to inconsistent grading or misleading product descriptions that product teams can fix.
Common pitfalls
- Charging for returns without improving size guidance.
- Treating all multi-size orders as abuse.
- Inconsistent sizing between styles, which encourages bracketing.
- Not measuring bracketing separately from general return rates.
Frequently asked questions
Is bracketing the same as wardrobing?
No. Bracketing is buying multiple versions to find the right one. Wardrobing means wearing an item and then returning it as if unused.
How do retailers reduce bracketing?
By improving size charts and fit recommendations, showing fit details from other customers and making sizing consistent across collections.
