The hacks
Vertical outfit builder with swipe-to-add
Top, bottom, accessories in a vertical stack. Each section swipes horizontally to show options. One tap per item. The outfit builds visually as items are added.
Mobile-first capsule tier selector
Three large buttons: "2-piece ($74)," "3-piece ($99)," "Full outfit ($129)." No dropdown menus. No scroll-to-reveal. Each tier is one tap. Tiergain renders mobile-first capsule tier selectors.
Sticky "complete the look" bar on mobile product pages
Sticky bar: "Complete the look - add pants + belt ($67, save 14%)." Visible as the customer scrolls through product images. The bar persists without blocking the content.
Mobile cart with outfit completion suggestion
Cart has a shirt. Cart drawer shows: "Add matching pants for $38 (save 12%)." The suggestion inside the cart drawer catches the customer at buy intent. Size is pre-matched.
One-tap post-purchase matching item on mobile
After mobile checkout: one big button - "Add matching scarf - $22." Mobile post-purchase must be one tap, one item. No carousels, no options. One matching piece.
Mobile threshold banner with specific accessory suggestion
"$22 away from free shipping - add a belt?" Compact banner above the fold with the specific product name and price. On mobile, specificity converts better than generic threshold bars.
The mobile outfit builder must work with one thumb
Hold your phone in one hand. Can you build an outfit with just your thumb? If any step requires two hands, pinching, or horizontal scrolling through a grid, the builder will not convert. Design for the thumb.
