ebure Sheer Cotton Acetate Crew Neck 3/4 Sleeve Rib Knit Pullover Worn Once This crew neck top is a great piece with a sizing that doesn't cling too much to the body, offering a more polished look than a t-shirt while still fitting with any bottoms! Tucking it in is the style this year for a clean look. The three-quarter sleeves are also great for subtly covering the upper arms.
