We provide standardized, customer-centric return and exchange services for all casual apparel products including t-shirts, hoodies, sweatshirts and jeans, offering a 30-calendar-day valid return and exchange window calculated from the official order delivery date. To fully qualify for return or exchange application, all submitted apparel items must remain completely unworn, unwashed, unaltered, unstained and undamaged, retaining original brand-new retail condition with no body odor, washing traces, fabric pilling, surface stains, artificial damage or private modification marks. All original factory accessories must be fully intact, including complete outer packaging bags, protective films, hanging tags, brand labels and instructional cards without loss, damage, disassembly or replacement traces. Custom personalized printed garments, privately altered sized products, customized style items and final sale clearance goods are strictly non-returnable and non-exchangeable due to personalized production attributes and special promotional sales regulations. As close-fitting daily textile products with strict hygiene standards and secondary sales restrictions, any apparel that has been worn for daily use, machine or hand washed, stained by sweat and dirt, artificially cut and modified, improperly maintained or damaged by personal operation is ineligible for return and exchange. Products with fabric deformation, loose stitching, pattern peeling, serious fading, artificial pilling and obvious usage traces will be directly rejected for return applications to uphold unified product hygiene standards, quality consistency and fair shopping rights for all customers. To initiate a valid return or exchange request, users must submit an official application through the website background portal with a valid order number, detailed problem description and corresponding real product photos. After professional after-sales team review and formal approval, customers will receive an official return authorization number and standardized return shipping guidelines. Customers bear full independent responsibility for all return shipping fees and logistics transportation risks unless the products have confirmed factory manufacturing defects, official shipping errors, verified transit damage or missing original accessories attributable to our internal team. We strongly recommend customers use formal trackable logistics services and fully restore the original dust-proof, wrinkle-resistant and sealed packaging during return shipment to prevent secondary fabric contamination, extrusion wrinkles and surface damage that will invalidate return eligibility. After receiving and systematically inspecting the returned products to confirm full compliance with official return standards, we will process full refunds or store credit exchanges within three to five business days. All refunds are issued through the original payment channel, and the final fund arrival time depends on the processing efficiency of the corresponding financial institution. Direct exchanges for different sizes, colors, patterns and styles are not supported; qualified returned items can only be converted into store credits for subsequent new product purchases. For unresolved return and exchange inquiries and special after-sales situations, users may refer to the official FAQ page for detailed professional guidance and standardized after-sales support services.
