This 95% cotton/5% spandex quarter length sleeve T-shirt by Christine Alexander is pure white and embellished with Swarovski elements covering a large area of the top front of the T-shirt. It is a size Medium, 3/4 sleeves, and new with a tag. It is perfect for casual or more dressy occasions. The measurements are: 15 1/2" top of sleeve to bottom of sleeve; 17 1/2" underarm to underarm; 16 1/4" from underarm to bottom of hem and 24 3/4" from shoulder to bottom of hem. T-shirt runs smaller in my estimation. It does have spandex and stretches. It would look perfect under the Christine Alexander black or blue jacket.
