Thank you for viewing! This is an all-in-one pants-style dress! It's adorable and can be styled in just one piece♡ I've worn it twice and it's been dry cleaned. It's a size S, but it has a relaxed fit, so it can easily fit someone who usually wears a size M◎ The waistline is defined by the seam, and it has an elastic waistband, so it's not tight. Please purchase if you understand that this is a used item.
