To wear this Astrid dress, simply put it on like any other dress. You can adjust the tie closures to your preferred tightness. For a casual look, pair it with sandals and a woven handbag as mentioned. For a more formal occasion, add some heels and a nice necklace. When it comes to maintenance, it's best to follow the washing instructions on the label. Usually, a gentle machine wash with cold water is a good choice. Avoid using harsh detergents that could damage the fabric or fade the floral print. Hang it to dry to keep its shape. And always iron it on a low - heat setting if needed.
