My sister in-law looks in her late 50s, she looks a lot like Sophia Loren. I have known her for over 40 years and the only thing she has done is dye her hair. She still looks good in jeans and a T-shirt at 81.
And Lulu was never chubby. She has a round face but has always had a tight jaw line with no hint of double chin and a slim body. I spoke to her in the 60s
