I've noticed a huge difference since turning 60 a few years ago. I'd always thought I'd breeze through my 60s, as I had my 50s. Facially that's pretty much the case, but not bodily! Little issues with feet, joints and circulation that I've had all my life have worsened, meaning I have to be really careful with footcare and shoes or I can't walk for a week. Hence the trainers.
My colouring, which was dark hair/pale skin, isn't so high contrast any more, so intense colours can look garish rather than cheerful or dramatic. Softer colours, which I might previously have dismissed as boring, now look much better on me.
As the smoothing effect of collagen recedes, my body shape (long legs, small bum, not much waist, big chest) has kind of exaggerated - legs thinner, butt disappeared, middle thicker, boobs bigger. It takes a lot of work with exercise and diet to maintain some kind of visual balance. And tbh if I hadn't married a younger man, I probably wouldn't try so hard to do so😅
So I'd just say, enjoy your 50s while you can OP, cos biology catches up with us all sooner or later! I think @J23 has some good suggestions.
