You can wear it for both formal events like business meetings and casual outings. To keep it looking good, follow the care instructions on the label. Usually, a gentle machine wash or dry - cleaning will do the trick. Avoid exposing it to sharp objects to prevent snags. If there are any wrinkles, you can iron it on a low - heat setting.
