To wear this blouse, simply put it on over your head. It's great for both casual and semi - formal occasions. When choosing a size, refer to the size conversion table provided to ensure a proper fit. As for maintenance, remember to machine wash it in cold water and tumble dry on low. This will help keep the frills looking nice and the material in good condition. Avoid using hot water or high - heat drying, as it may damage the fabric or cause the blouse to shrink. Also, be gentle when handling the frilled parts to prevent them from getting damaged.
