Hi Roxanna,
I'll join the chorus and sing these jeans' praises; they are truly spectacular on you! Like others, I would never have guessed you are petite--and this, from a petite pear, herself, albeit 5'4" to your 5'3". We share similar fashion challenges. although (as I say too much on this forum), I am decidedly short-legged. But discovering my VERTICAL body type has changed EVERYTHING for me; conventional advice for petite pears doesn't work iif the long torso/short leg ratio isn't taken into account (like full skirts with fitted waists, which make me look like either a bell or upside down cupcake).
What this means for you: You say you are short-waisted, which may be true (my eye isn't that trained), and if so, is opposite me. In that case, you could try matching your belts to the color of your tops rather than your jeans. Do experiment, as you will discover why you have preferred one way or another over the years.
As for tops: Conventional pear advice still works here, especially with the higher-rise jeans (the trick to elongating the leg line, as well as the flare bottom that balances the hips, and of course, heels). I love the advice to put the emphasis on "I": lighter, whiter, brighter, wider on top. Boat necks are great, as are horizontal stripes. The standard preppy J Crew look (for lack of a better visual) that Kate Middleton recently wore is an easy pick for you in any color combo you like. There should be inexpensive "replikates" at Gap, Old Navy, etc. I also LOVE what I will call the "Aida slouch," or oversized Tees with slight v-necks (drawing the eye downward) half- tucked. Banded bottom sweaters (cowl necks to add bulk on top come to mind) with or without faux-tucking work, as do adding scarves to just about anything (you have to play with scarf shape--I like infinities and Vs with tassels that don't go beyond my waistline). Also, keep the arm-length at 3/4 or elbow at longest to create a horizontal above the hip.
Finally, notice that none of the above suggestions are particularly 70s. Since skinnies are anathema to me, I find I can wear flares that hug my thighs with anything others typically pair with skinnies, including tunic tops that aren't too long or are faux-, partial-, or diagonally tucked. Of course, bell sleeves and peasant blouses take you back to the decade you wish to avoid--so eliminate those if you wish. And on color: choosing the same or neighboring colors (grays, greens, and blues of the same intensity as the distressed denim ) will elongate the entire body in a column of color (my handle, my first fashion trick)! That's all I got! Hope it helps!!
