This jumper is designed for straightforward integration into your wardrobe. No complex setup is required. Its regular fit ensures compatibility with most casual and semi-formal attire, easily layered over shirts or undershirts. The primary care instruction to ensure longevity and shape retention is to dry flat; do not hang. Hanging this jumper, especially when wet, can cause it to stretch or lose its intended shape. For washing, while not explicitly detailed in the product information, typically cotton-merino blends benefit from a cool wash on a gentle cycle, using a mild detergent. Always refer to the garment's care label if available for specific washing temperatures and instructions. Store folded flat in a drawer or on a shelf rather than on a hanger to prevent shoulder bumps or stretching.
