Weight, it’s the number one thing that’s ageing, too thin or too fat. A matronly bust atop a big belly. Or a thin body with no muscle tone. We should aim for a healthy bmi, irrelevant of where on the bmi scale be it 19 or 24 that suits our frame, with muscle tone, is the most youthful.
good hair, in good condition. With a good cut/style, no washed out colours, brassy colours, dry ends, massive roots.
good skin, this doesn’t just come from skin care, it comes from diet and lifestyle, being hydrated, eating enough protein, vegetables, fruit, limiting alcohol, sugar and caffeine. Skin is also your body as well as your face, so moisturising all over to keep it supple and bright.
good make up if you chose to wear it, subtly done to highlight the positives and blur the negatives, nothing harsh, fake or caked.
good eyebrows, thin , sparse or over drawn in is never good.
good clothes, quality pieces, in a current cut, in a quality material that fit properly. So maybe wide leg trousers, rather than skinnies, midi dresses rather than knee length etc etc, whatever suits you, not going for fashion, but going for a nod to current, depending on age, also aiming for elegant and modern, is better than going for cheap fashion, in crap materials and cut. Try vinted for higher end high st. Like Reiss, me + em, max mara etc if on a limited budget.
subtle perfume if you like perfume, or a scented body lotion, something you love the smell of, stays close to the body, and makes you feel good.
snd importantly exercise if you’ve time, exercise gets the blood flowing, brings a flush to our skin, and makes us feel better, at least after if not during.
make small changes one at a time, it’s amazing the difference some self care and love can make to our outward appearance and subsequently how we feel about ourselves.
