Carter, I love these looks so very much! For anyone, but especially for you, because this is so authentically you!
Without reading the other responses first, here is what I see in these looks:
Generally: I puzzled over why these looks weren't retro, because the slim pants have been worn by every style icon from Marilyn Monroe to Jackie O to Audrey. I think it's the rise: they would have worn high-waisted pants back in the day.
I also see where the hairstyle is every bit as much a part of the look, as the style of top, or pant, or shoe.
Specficially, from top to bottom:
Hair: out of 20 looks, 14 of these had the hair worn down, mostly in soft waves. 4/14 look deliberately blown out or flat ironed. Of the remaining six (two you can't see at all), the updos look soft and a little mussed.
Makeup: Lip colors were mostly nudes, soft corals and soft reds. Mostly nudes though.
Jewelry: I only see one pair of 'statement' earrings out of 20 looks. The rest look like studs, or I can't see them at all. I only count 5/20 with necklaces, 3 of which are long, dainty, with a single minimalist, bold pendant, and 2 are dainty and circular and hit at the collarbone. Altogether minimalist. Bracelets and watches are stacked and monotone (monochrome?), and again, mostly sleek and minimalist. Or a large, sleek wristcuff.
Tops are all relaxed, but a bit fitted, and none seem to be cropped or tunic length. They all hit somewhere on the hip, whether tucked in, or worn out.
Pants, regardless of length or bottom, appear to be slim-fitting, flat-front, and mid-rise. In almost all of the looks where the top is tucked in, there is a classic leather belt of mid-width, not narrow or wide.
Handbags are just that: held by the hands as a clutch or handled bag. Not crossbody or over the shoulder.
Shoes aren't extreme or statement. They have rounded toes or soft points, and are mostly the sort you slip your foot into: only 4/20 (that I saw) had any straps or buckles.
