I’m much the same. I guess we just have to grow old gracefully. I accept that I’m not going to be a young attractive woman again (I didn’t look too bad 15 years ago) and so I go for the more mature look, on the odd occasion I get a chance.
As far as the waist is concerned, I find a high-top pantie girdle at least smooths it all out, and hip pads and D forms make my waist look more proportional. If that’s not enough, a lace-up waspie is surprisingly comfortable and can take two or three inches off.
