I recommend Chanel No. 19, famous for its luxurious scent!! You might find it a bit strong, but its greatest advantage is that it becomes subtle and lasts for a very long time as time passes!! It is a very sophisticated fragrance, and It's a perfume that goes perfectly with the cold winter!!
You know perfume is a real must for thick coats since you can't wash them often, right? Haha. I highly, highly recommend Chanel No. 19!!
