The most interesting parts of her outfits are how common combinations become less expected. Maybe it's the removal of trends from the bodies that commonly occupy them. The knit dress, thigh high boot pairing is often seen via Instagram baddie culture where the body type is distinctly different. It could also be the fact that the colour scheme is relatively monochrome, or maybe the simplicity of the whole look. Only having as much as is needed to be dressed and out of the door. No extensive contouring, not extensive accessories.
It could also be none of these things. As much as I want to wax poetic about what is really interesting, I will save that for another time. Uni has killed my brain.
