To wear this blazer, simply put it on over your shirt or top. It can be paired with jeans for a casual look or with dress pants for a more formal occasion. When it comes to care, follow the washing instructions on the label. Generally, it's best to machine - wash it on a gentle cycle with cold water to preserve the quality of the cotton - polyester blend. Avoid using bleach as it may damage the fabric. Hang it to dry to prevent wrinkles. Before wearing it again, you can use a low - heat iron to smooth out any creases. Always check the size chart before purchasing to ensure you get the right fit for your body.
