CARE GUIDE
To preserve the integrity and longevity of each piece, we recommend hand washing in cool water.
If machine washing is preferred, please select a gentle hand-wash cycle to protect the fibers and maintain the fabric’s structure.
Always air dry and avoid tumble drying, as heat may compromise the quality of the materials.
SIZING
For the most comfortable and flattering fit, we recommend sizing up, especially if you prefer a more relaxed drape or intend to layer. Your usual size will deliver a sharper, tailored look.
94% of clients selected their usual size and confirmed an excellent fit, while many chose to size up for added comfort.
For precise measurements and detailed guidance, please refer to the Size Guide located above the size options.
