#1 is outstanding. Outstanding is my version of killer.
#2 I have a slight preference for this version of the first version of the culottes outfit. Perhaps it is the 70s vibe that resonates with me but whatever it is, to my eye it really works. I also have a slight preference for it with the necklace. I am really feeling accessories these days and I like to break up the black. I know your style can lean more towards simple and elegant though so you may prefer it without. Both are extremely stylish
#3 I have a slight preference for the tucked version. You have legs that go on forever so why not play them up a bit. I find the vertical stripe on the shirt is also elongating so it doesn't seem disproportional to me.
#4 I have the same issue with pants that are ankle length with boots and just let them catch on the back of the booties. It gives a bit of scrunch from the back and they still seem to lay nicely in the front. I prefer the full length for proportions.
Your style has shifted ever so slightly and is even more glamorous and polished than it was before. You look fabulous in everything.
