To use this suit, simply put on the oversize T-shirt and the matching shorts. You can wear it for casual outings, lounging at home, or other relaxed occasions. When it comes to maintenance, always follow the care instructions. Machine wash it in cold water with similar colors to prevent color bleeding. Avoid using bleach as it can damage the fabric. Tumble dry on a low setting to keep the shape. Do not iron or dry clean the suit as it may cause shrinkage or other damage. Check the size guide carefully before purchasing to ensure the best fit. Remember that the measurements on the guide are taken when the products are laid flat, and there may be a slight variation in actual products.
