When putting together an outfit consider what you would like to communicate with your audience. Do you want to express authority or do you want to be accessible?
It all boils down to what percentage of your ensemble is darker colors or lighter/softer hues. Outfits with the majority of pieces that are of darker value will add authority and stature vs. softer/lighter colors illustrates openness.
Or in this instance just switching up the blouse changes the message of softer vs. stronger.
