Underwear is one of the highest-fit subscription categories in apparel — high replenishment, high repeat behavior, basics and novelty in the same catalog. But most brands run “subscribe & save” on vitamins-first platforms that weren’t built for sized variants, rotating prints, or group subscriptions.
Dough Dog is Shopify-native, inventory-aware, and runs both replenishment basics and rotating prints in the same program — with the variant-level inventory awareness sized products require, plus Group subscriptions for matching pairs, couples, and multi-packs. 1% of subscription revenue + 19¢ per transaction. No monthly fee. Launch in under 12 hours.
They optimize for reordering. We optimize for anticipation.
The underwear-subscription capabilities standard platforms can’t model — and Dough Dog ships natively.

Basics ship the same size on a fixed cadence; prints rotate through your catalog — both under one subscriber, one billing.
Every pick checks live stock for the right size before charging — no out-of-stock email after billing.
Multi-packs, matching for couples (same pattern, different fits), or tops and bottoms shipped together as a coordinated set.
The subscriber never receives a print they already have — the Selection algorithm excludes past picks across their lifetime.
Bundle a bra, a pack, or a seasonal item into an upcoming shipment. Prints, cuts, sizes, and fit are set once and used every cycle.
Core basics every 60 or 90 days — the same size, every cycle, on autopilot.
A new print every cycle across your catalog, filtered to never repeat what the subscriber already owns.
Partner matching (same pattern, different fits) and bundle subscriptions — underwear + socks, or underwear + bras.
