REISS Oakley Button Belted Linen Blend Midi Skirt in Ivory - no brand/size tag but please see measurements to ensure a good fit but I think it's a size 0. Item is NWOT, still has extra button hanging on care tags.

The Oakley midi skirt in ivory is crafted from a linen blend for a lightweight wear. It’s designed to sit high on the waist with a self-tie belt to sculpt the figure. A concealed button closure is added for a vintage feel. Wear with a vest top and heels for a feminine daytime edit.
