Zimmermann silk deep plunge v neck black romper - size 1-mesh patterned textured

Worn a couple times only. No damage. Please use measurements for accurate sizing. This is a Zimmerman size 1!!! I would say it fits like a small overall. I wear a small-medium in the last photo & it’s just too small for me. Top has flexible boning. Zipper up back. Straps are not adjustable. Really beautiful!!
