Product Insights
Miiyu's Patterned Flowy Long Nightgown merges premium design details like adjustable tie straps and side vents with a moisture-wicking modal-organic cotton blend that absorbs 50% more moisture than cotton and stays buttery soft after 50+ washes, delivering a low cost-per-wear; the main tradeoff is that lighter colorways are semi-sheer and the garment requires washing in a mesh bag and ironing on low heat to prevent pilling and shine.
