Size...M Shoulder width...34 cm Body width...39 cm Sleeve length...19 cm Length...80 cm *There may be slight variations due to amateur measurements. This is a basic navy dress from Zara. I am selling it because it no longer fits. It can be used for everyday wear or formal occasions. I've worn it about 3 times and it's been home-cleaned. I cut off the tag because it touched my skin. I think the material is a slightly thick cotton. The sleeves have tucks, so they are fluffy. It's cute. There are no noticeable major scratches or stains, but please understand that this is a used item before purchasing.
