This Emporio Armani blue cotton blazer is super versatile. To wear it, just button it up or leave it open based on your style preference. For an office look, pair it with a blouse and pants as mentioned. When you're out for a casual evening, you can wear it over a simple t - shirt. As for care, dry clean it to keep its shape and color. Avoid exposing it to direct sunlight for long periods as it might fade the blue color. And always store it on a wide - shouldered hanger to prevent creases.
