Is it better to wear a down jacket on both sides or on one side?

Double-sided, one or both sides are made of good coat fabric, which is comfortable to wear and not easy to stick to the clothes inside; Second, the different colors on both sides are changed, and the feeling changes, the wearing time is long, and the utilization rate is high, like buying two pieces, and the cost performance is high. Third, the number of dry cleaning is less in a year, and it is more cost-effective to wash both sides. My experience is for your reference. If necessary, I can consult a professional clothing dealer.
