Knee high boots - honest advice please

[EssexLioness]

I have some brown lace up boots similar to these.Had them for years and I adore them. However I keep reading that these are dated now. I am 43 and struggle to know what is stylish or how to put outfits together so would love some advice.
I have previously worn these with skinny jeans or knee length dresses. I’m guessing these would be dated looks? Is there a way of wearing them in a stylish way? Maybe with a midi dress?
I know I can wear whatever I want, but I am trying to look more stylish in general which is why I am asking. I have recently lost a lot of weight so my figure has completely changed and I am looking at overhauling my whole wardrobe.
I’m 5’4, size 12, hourglass with quite long legs and short torso

Have a look on the young people's fashion sites like boohoo 😂I don't have a clue either tbh

Chunky ankle boots seem to be in fashion atm see River Island

Culottes looks like puss in boots!

And this is a bad thing because…?

Also, knee length boots over jeans is pretty classic, it may not be what 20-somethings are wearing, but not everyone aspires to look like them.

I've got a couple of maxi a-line denim skirts that are crying out for tan knee high boots but alas my limbs won't support that fantasy!
