ShopMySize

Ask shoppers their size. Show only their size. Sell more, return less.

ShopMySize shows every first-time visitor a size selection popup. Once they pick their size, your store filters to show only products available in that size. Shoppers see only what fits, reducing decision fatigue and returns. Size preferences persist across sessions and sync to customer metafields for logged-in shoppers. Works with any theme — no liquid editing or developer needed.

• Size-filtered storefront — show only in-stock items that fit each shopper
• Email capture — collect size + email in one step, syncs to Klaviyo
• Full brand control — customize colors, copy, button style, and emoji
