To wear this shirt, simply button it up and tuck it in or leave it out according to your preference. It's perfect for holiday parties or casual outings. When it comes to care, machine wash it on a gentle cycle with cold water. Avoid using bleach as it might damage the crystals. After washing, hang it to dry to maintain its shape. Iron it on a low - heat setting if needed, and be careful not to press too hard on the crystal areas.
