Girls, navy, green, and black, long sleeve dress by Polo Ralph Lauren. The dress is designed to look like a long shirt with a skirt. The "shirt" part is a classic navy and dark green plaid pattern with an embroidered navy logo on the left chest. The skirt part is a classic, cotton pleated skirt in black. Made from 100% cotton so it's comfortable, breathable, and easy to clean

Size 6X. Exact measurements are as follows: Shoulders across - 13"   Underarm to underarm - 12.5"    Hips (where shirt ends) - 14.5"    Skirt bottom - 20"    Underarm to skirt hem - 17.5"   Center of collar to skirt hem - 21"

Good condition. There is some discoloring on the right sleeve. I stain treated and washed it but nothing came out. It looks like it could have been paint, close up picture at the end. The collar might also be a little stretched out on one side. No other damage or flaws. No rips or holes. 
Polo Ralph Lauren typically sells girl's long sleeve dresses for $69.50 and up
