French Sleeve Mermaid Rib Knit Dress This rib knit dress creates a smart I-line silhouette. The sharp V-neck that accentuates the décolletage is also a key point. The French sleeves make your shoulders and upper arms look slender. The self-fabric belt that cinches the waist adds a sense of contrast to the styling. The mermaid design with a fluffy hem leads to an elegant and feminine look. This is a reliable piece for adult women that will be useful for dates and special occasions.
