Building for constraints, not despite them

Observant customers deserve platforms that respect their practice

Undies sells intimate apparel to a diverse customer base, including observant Jewish customers who observe Shabbat. A standard eCommerce platform couldn’t accommodate this core requirement: the ability to respect Sabbath practice by preventing checkout initiation from Friday sunset through Saturday.

Beyond Shabbat Mode, selling intimates requires solving a specific problem: customers need to understand fit across a complex product matrix – color families, fabric types, sizes – without getting lost. They need guidance pages that actually help. And they’re buying almost entirely on mobile.

When you’re selling fit-dependent products, your platform can’t be generic. The interface that works for commodity retail breaks when customers need confidence in their purchases.
