Target AOV from $86 baseline with full stack
The apparel stack framework turns single-piece purchases into multi-item outfits. Hero piece sets the anchor. Accessories add perceived value. Capsule tiers compound the cart.
The hacks
Hero piece: one signature garment as the outfit anchor
The jacket, the dress, the signature top. One piece that defines the outfit. Everything else in the stack - matching bottom, accessories, extras - builds on this anchor.
Entry incentive: free accessory instead of percentage off
Instead of "15% off your first outfit," offer "buy the jacket, get a free belt." The belt costs you $8 and feels like $24. The 15% discount costs you $17.85 and builds no loyalty.
Capsule ladder: escalating rewards per outfit piece added
Buy 1: full price. Buy 2: free shipping. Buy 3: free shipping + free accessory. Buy 4+: free shipping + accessory + mystery item. Tiergain stacks all reward types in progressive capsule tiers.
Non-monetary bonus: limited exclusive or mystery item
Top tier: a limited edition accessory only available in the full capsule bundle OR a mystery item from the upcoming collection. Exclusivity and mystery both outperform bigger percentage discounts.
Size-matched outfit completion upsell
Cart has a medium jacket. "Complete the outfit - add matching pants for $38 (save 12%)." Size-matched suggestions convert at 8.4% vs 2.1% for generic recommendations.
Post-purchase matching item from the thank-you page
After buying the outfit: "Add matching earrings for $22 - one click." Fashion buyers at the thank-you page are still in styling mode. The matching piece is the easiest post-purchase sell.
The hero piece determines the AOV ceiling
A $42 t-shirt as the hero anchors the stack at $100-120 max. A $89 jacket anchors it at $148-200. Pick your highest-value signature piece as the hero. The anchor price sets the ceiling for the entire stack.
