Is DKNY a luxury brand?

Could you please clarify whether DKNY is considered a luxury brand or not? I've heard mixed opinions on the matter, and I'm curious to hear your take on it. From what I understand, DKNY is a subsidiary of Donna Karan New York, which is known for its high-end fashion designs. However, I'm not entirely sure if this automatically translates to DKNY being a luxury brand as well. Could you elaborate on this point, and perhaps provide some examples or criteria that define a luxury brand in the fashion industry?
