I need a clean, modern-looking site that lets visitors choose their preferred size and color, drop items into a cart, breeze through checkout, and leave a review once their shirts arrive. The overall aesthetic should stay minimalist— plenty of white space, sharp product photography, and an interface that works just as smoothly on mobile as it does on desktop. I’m open to Shopify, WooCommerce, or a custom solution; what matters is that product variants and reviews are handled natively, pages load quickly, and I can update inventory or run promotions without touching code each time. To make sure we’re on the same page, your hand-off should include: • A fully responsive storefront with product, cart, and checkout flows tested end-to-end • Variant selectors for size and color tied to real stock levels • A reviews module that I can moderate from the back end • On-page SEO basics in place (clean URLs, meta tags, alt text) • A short video or written guide showing me how to add new designs and fulfill orders Launch-ready polish is the goal here, so please factor in one or two revision round for tweaks to typography, spacing, or color accents while keeping the minimalist vibe intact.
