How does a fashion store in the GCC get repeat customers?

By reaching the customer at the moment the first purchase runs out, through a channel that does not charge per message. Almost every store has the timing data and spends the reach budget anyway.

The mechanics of a second order

Work out the median gap between first and second order. Whatever that number is, the reminder belongs slightly before it — after it, the customer has already solved the problem somewhere else.

Winning a customer costs money and selling to them again costs almost nothing, and most budgets are spent as though the reverse were true. For a fashion store in the GCC, the answer turns on one thing in particular: Fashion carries the highest return rate in retail — sizing is guesswork on a screen — so the margin has to survive a third of the order coming back.

What is different about the GCC

The GCC is not one market. Payment habits, delivery norms and language expectations differ enough that a single approach underperforms in at least one country.

Payment preference varies by country more than most planning assumes.

Discounting to grow trains people to wait for the discount. It works once.

Where a mobile app comes into it

Repeat rates in fashion are strong once a customer trusts the sizing, which is exactly the behaviour an app is built for.
