After a bit of browsing I have come to the conclusion that Tricia Cusden is stylish, conventional, age appropriately dressed LOL. Not my style at all.
By the time we reach 60 we are all so varied, some do not look a day over 45, some look over 70. We have developed a style over the years that goes from utterly eccentric to staidly suitable for our age and everything in between.
It is impossible for anyone to recommend styles of clothes, make-up etc to older women we are too varied in every way. No-one would do a fashion and style article aimed at women in the 15 - 50 age group, why expect older people in such a varying age group to share the same style.
I think the best thing to do is forget any preconceived ideas of what is suitable for your age and take your self out to a large shopping centre and wander the shops seeing what is available. Make sure you look in all the shops aimed at younger women. I like H&M, Monsoon, Fat Face and Next. None of them seen as aiming at older women. look for clothes you fancy and flatter you and to h*ll with age.
