Thank you for viewing. I purchased this on Mercari several years ago, but after trying it on, I was concerned about how it looked on my stomach, so I kept it in storage. The dress underneath is tight if you have a protruding stomach, so I think a size M, which is a bit slimmer, would suit you better. The length will be around the knee when worn. Although you can't see it in the photos, it has a tasteful scattering of glitter and is elegant. It's in beautiful condition. I will include the measurements provided by the seller on Mercari. ◆ Jacket ◆ Width: Approximately 44cm Length: Approximately 51cm Shoulder width: Approximately 37cm Sleeve length: Approximately 58cm ◆ Dress ◆ Width: Approximately 43cm Length: Approximately 92cm Thank you very much.
