Diana, Princess of Wales proved that Lady Dior has been a timeless classic bag.
As a royal public figure, she always looked elegant and classy in her clothing choices. And I believe that Lady Dior (medium size) was one of her favourite handbags at that time since the bag had accompanied her to various royal engagements or duties.
This is one of the inspiration that has influenced me to get my first Lady Dior (large size) for my self birthday present this year (check here).
