This...is...fantastic! I have a sleeveless dress but I am self conscious of my arms. I lost 110 pounds and have loose skin. I wanted something to cover my arms, but that did not cover up the dress at all. Even some shrugs & boleros cover 3/4 of your back. This is, as other people have said, a tube with a hole in it. Its so slick I love it. Like people are going to want to know where you got it if you buy it because its so unusual. It literally goes up to your armpits then around your back. Very minimal. Very hip. Very sexy.
The fabric is fine. Of course it doesnt look like it cost $100 but its not bad.
