Below is the official product description:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This dress features a design that combines a gingham check blouse with a knit tube dress. Puff sleeves with drawstring gathers add a soft, voluminous look. The roll collar can be tied in a ribbon at the back, creating a charming impression from behind. The waist is defined by a ribbed section, offering a corset-like waist-cinching effect for a flattering silhouette. The narrow skirt shape balances the overall look, adding a touch of sophistication. For footwear, pair with delicate pumps or mules for a feminine look, or with sneakers for a more casual style. This is a statement piece perfect for summer, suitable for both casual and formal occasions. *All images are of samples. *The color in the close-up fabric image is closest to the actual product. *There is a 5cm difference in total length between sizes S and M. *The color in the worn images may differ from the actual product due to flash photography; please refer to the zoomed-in fabric images for accurate color. *The actual product color may vary depending on your device's screen settings.
