This is a blue dress I bought from GU. It's sleeveless with a skirt that falls just above the knee. The size is M. The material is 100% polyester for both the outer and lining. I've only worn it once and washed it, so it's still in great condition. It's probably almost the same as when I bought it. Here are the flat measurements: shoulder width 33.5 cm, length 80 cm, width 40 cm, sleeve length 6 cm. It has a soft black lining inside, so you don't have to worry about your undergarments showing through. #GU #GU #Casual #Dress #Sleeveless #Blue #Blue #Stylish #LooksExpensive #Cute #Women's #ForSummer #Summer Size...M Color...Blue Pattern...Floral Silhouette...Flare Season...Spring/Summer Stains/Tears/Smells...None
