To wear this shirt dress, simply put it on and adjust the self - tie waist to your liking. You can wear it casually with flats and a shoulder bag when you're out and about. For a more formal look, you can add heels and some jewelry. When it comes to maintenance, check the care label. Usually, it can be machine - washed in cold water on a gentle cycle. Hang it to dry to avoid shrinking. Also, avoid direct sunlight when drying to keep the blue color vibrant. Be careful when ironing the puff sleeves to maintain their shape.
