What do older women wear in summer?
I never know what to wear to be cool and comfortable yet age appropriate (young looking 60s) in summer. Knee-length shorts recommended in style guides for older women look a bit lady-golfer for my style (natural, feminine) and my shape (short body, long thin legs, bit of a tummy) looks better balanced in shorter shorts with a longer, loose top over them. I don't work, so most of my wardrobe is casual.
Take a look at my article on "how to dress well and look great at any age"
and the related articles listed at the bottom.
The main trick is to cover the parts of you that are a bit saggy and emphasize your best points!
