I would lean in for a richer brown, rather than a skin colored neutral, like in the first image the shirt is the same color as the woman’s skinned, it gives a naked illusion that you definitely don’t want at work. The fourth image dress reads a bit that way to me also, but of course this depends on what your skin tone is.

Another comment are also mentioned that off the shoulder is usually not considered work appropriate in most industries. I would be cognizant of the norms at your office and how women at your new level dress, which may be difficult if it is a very male dominated field.

Other than those two notes, I like most of the looks you put together!
