To wear this blazer, simply button it up over a white blouse and pair with slim - fit trousers for a classic look. You can also leave it unbuttoned for a more relaxed style. When it comes to care, follow the washing instructions on the label. Usually, it's best to machine - wash it in cold water on a gentle cycle. Avoid using bleach as it may damage the fabric. Hang it to dry to keep its shape. And don't forget to iron it on a low - heat setting if needed.
