Sonia rykiel pleated dress w/pockets

Bought this at a sample sale in London. There’s no size or fabric composition tag. The fabric feels like a super high quality gaberdine. The size feels like a 4. I’m 5’10, size 4/26 jeans, 32dd and it fits well. Missing the hook for the hook and eye at the top of the back zipper. I’ve never worn it. Super cute with the pockets Veronica beard reiss maje Sandro Isabel marant Emerson fry
