The collar is removable. Actual waist measurement is 37.5 cm, length is 97 cm, and the distance from the armpit seam across is 43 cm. The collar is adorned with numerous colorful, large and small Swarovski crystals (with a Swarovski tag), making it sparkle beautifully. The collar can be removed with small buttons, transforming it into a normal round-neck dress. The fabric is of high quality and firm, typical of COTOO, and this dress is clearly a cut above the rest. ● Size: 40 (equivalent to size 9-11)
