SopliagonWomen Cotton and Linen Shirt Dress Casual Loose Maxi Dresses

False advertising? is this cotton and linen or cotton and polyester. what are the actual materials of this item?

why does it state linen and cotton when it does not contain a single thread of linen but it has polyester?

Is this dress "linen", as listed in the headline? Is it cotton/linen, or cotton/polyester as the seller listed in 2 additional descriptions. Thanks.

How long overall is the Medium? One reviewer said she was short and it was knee-length. I need it long, to protect from the sun on my boat.
