To use this sundress, simply slip it on over your head and adjust it to your comfort. It's perfect for a casual day out in summer, like a picnic or a stroll on the beach. When it comes to washing, you have two options. You can hand - wash it gently to keep its fabric in top shape, or use a machine wash on a gentle cycle. Make sure to use a mild detergent. After washing, let it air - dry to prevent any shrinkage. Also, avoid wringing the dress too hard as it might damage the floral pattern. And remember, it takes 15 - 20 business days for the product to be delivered, so plan your summer outfits in advance!
