Fashion Shopify Store Development

I need a complete Shopify build for a clothing-and-accessories brand. The look must stay clean, modern, and fully responsive so shoppers have the same smooth experience on phone, tablet, or desktop. Clear navigation, intuitive collection hierarchies, and fast-loading pages are essential because most of my traffic comes from mobile social ads. On each product page I want two must-have elements baked in: a size guide (preferably in a pop-up or expandable block) and a verified customer-review section that supports photo uploads. Credit and debit card processing plus PayPal checkout have to be live at launch; please configure them inside Shopify Payments so I can start taking orders as soon as we go live. Deliverables I expect: • Custom theme design and set-up inside my Shopify account • Responsive layout testing across major devices and browsers • Product page template with the size guide and customer reviews working out of the box • Navigation, search, and collection filters tuned for apparel shopping • Payment gateway configuration (Credit/Debit cards & PayPal) and a quick walkthrough so I can manage refunds and payouts on my own • Launch support and a short handover video or live call outlining theme sections, metafields, and basic maintenance If you can suggest extra optimizations—like adding high-resolution image zoom or automated upsell blocks—I’m open to hearing them, but they’re not mandatory for this first milestone. Looking forward to seeing how you’d approach the build and timeline.
