When you receive your one-shoulder chiffon bridesmaid dress, just put it on like any other dress. The spaghetti straps go over your shoulders, and you can fasten the buttons at the back. For cleaning, it's best to follow the care instructions on the label. Usually, a gentle machine wash or hand wash in cold water is recommended. Avoid using harsh detergents that could damage the chiffon fabric. If you ordered a custom size, make sure to double - check the measurements you provided to ensure the perfect fit. And don't forget to check the return policy in case you need to make any changes.
