Zimmermann Cassia Bandeau Midi Dress in Musk Floral. Zimmermann Size 0. I purchased this dress on Poshmark previously and it had been worn a handful of times before. It has been worn a couple of times since then and is still in great condition. There are a few tiny dots where the pattern on the dress has come off of the linen fabric and that is shown on the last image- it is not very noticeable especially when the dress is on.
