I have always worn a lot of pink as it has always been a colour that suited me. Depending on garment and fashion, I have - and still do - wear every shade of pink from palest pastel pink to fuchsia.
Age appropriate' dressing is not a concept I recognise. I am heading for 80 and shop in all the mainstream clothes shop and it is not unknown for me (78), DDiL (50) and DGD (15) to all be dressed in similar styles.
I never wear navy blue or black, neither colour has ever suited me, though I like grey. But I like to open my wardrobe in the morning and see a feast of colour in front of me. I have always loved autumnal colours in all their glory, they really suit me, and it is just coincidental that this weekend I bought a dress for DD's graduation. It is an abstract leaf pattern in rose pink, cream with soft shades of brown such as taupe/coffee/chocolate , to quote the OP. I bought it in a supermarket in France.
