Personally I am willing to pay a lot for my hair cut, to have it styled and easy to maintain. I see so many older women who look like they have given up and have been badly shorn or permed. I think over dyed, dark, hair can be very ageing.
As for foundation make up, less is more in older age. Thick foundation accentuates the wrinkles! I think a very thin layer of foundation and a very light tan type lotion can give a healthy looking glow. But age is just a number and it's what is going on inside that says more than the outside....and smoking and drinking heavily are very ageing for the skin.
For clothes I think investing in some timeless, well designed items from more upmarket designers works well...and those can be found on Ebay at a fraction of the cost. Longer shift linen dresses in self colours accessorised with scarves is an ageless look. Then you don't have to worry about cellulite!
IMHO bright jazzy designs are not for older women, and showing a wrinkled cleavage is not nice.
I read this in a book called ,'Senior Moments'.....
At 20 we worry about what people think of us; at 40 we don't care what others think about us; at 60 we realise they haven't been thinking about us at all'.
