Customers come once every 1-2 months, spending €100-250. Every lost customer is a serious hit.
A basic 3% cashback won't cut it here — too little. Progressive scale: 5% up to €500 spent, 7% up to €1,500, 10% above + early access to collections.
Push shouldn't say "come visit us" (too pushy), but rather "New collection — first access for VIP members" or "You have €60 in bonuses, sale starts tomorrow."
Referral program: "Bring a friend — €25 for both." In fashion, recommendations work better than any advertising.
