Among my contemporaries, I have seen in recent years how great the transformation is that women go through around the age of fifty. Children leave the house, parents need looking after or die, and our own bodies change. Society reacts differently to women in their fifties than to women in their thirties. It is a transition phase and that often can entail uncertainty, especially about your appearance.
My vision on style and clothing around the age of fifty is that there is no reason to shine less and to emphasise our femininity any less, just because your body changes slightly. Is your blooming period over? Nonsense! Your clothes should reflect who you are and make you feel confident and good. Maybe this is just the time, right now!
