When you receive your burgundy long mermaid bridesmaid dress with spaghetti straps, first give it a gentle shake to remove any wrinkles from shipping. Before wearing, make sure to try it on and check if the size fits well. If you've ordered a custom - sized dress, it should fit like a glove. For the big day, pair it with some elegant jewelry and high heels to complete the look. When it comes to cleaning, it's best to take it to a professional dry - cleaner to keep the satin fabric in good condition. Store the dress on a wide - padded hanger in a cool, dry place to prevent creasing and damage. And don't forget to check the return policy if you have any issues with the dress.
