I thought for sure you were at least 5'8", I had no idea you were a petite sister (I need petite jackets but regular pants, I have a really short torso and short arms!).
I think all of this is fantastic and the grey and brown jackets that aren't being loved as much as the other read as professional in a good humble way. Not like big ego professional which loud colors can subconsciously convey.
I also really like the color blocked pencil skirt and the b&w Nexx blouse, although the loose in the shoulders look of the blouse does make it look a more casual than all of your other choices.
