V-Neck Linen Maxi Dress

I purchased the goldfinch medium dress; there were no labels as to the material content. However, the dress looked and felt like a linen or a cotton linen blend as advertised. The dress was unlined , felt like a sack on and puckered on me above the breast so I ordered a second shift in a large in available white and was surprised that unlike the goldfinch color , the white dress was fully lined. Again, no material content label was located and although the area above the breast laid flatter, the arm holes were bigger. I decided to return the goldfinch in medium and keep the white in large. The white shift feels good on with the added weight of the lining , is about the same length as the medium on me , and pairs well with a sweater or jacket and multiple types of foot ware. I would purchase a large in black as well however, it doesn’t appear in the pictures to be lined. The difference in the feel of the dress between being lined and unlined is huge IMO. I am 5’6” 162 pounds , 34 DDD. Material looks and feels quality .
