This is a shirred sleeve gathered dress. The back style features a silver zipper accent ^-^ I purchased it from a select shop. The skirt has a lot of fabric and a voluminous silhouette, which is cute, but the fabric is wrinkle-resistant, and I don't think the weight is too noticeable. You can enjoy it throughout the long seasons except for mid-summer. It has convenient pockets! The waist is also wide, so I think pregnant women can wear it too ♩ My tastes have changed, and I no longer use it, so I'm selling it.
