Why not ?
The change of personality of Sophia can go through a external change of mood, vocabulary (bold/defiant), hairstyle (especially the color or length*), clothes (sexier), makeup, dominated/dominant behavior, ...
* A hair shortening is symbolically stronger than a simple coloring.
However, this change of hairstyle is only motivated by boredom in the developer, and for technical reasons for animation.
Unlike the last 'style' poll, where you had to choose the clothes (two opposite style : rocky or classical) for Sam's concert, it was just for an event, now it's gonna be several (playable) days I think, and it was obvious from the beginning, that we were going to have no 'radicalism' in the proposals, because Sophia can always continue the good wife path.
If only B solutions are chosen, people are likely to turn to the most consensual solutions (B2 / B3). B2 changes almost nothing.
B3 would be my choice, to show a little change in Sophia's personality.
B2 will be good too... especially if Sophia's tan is slightly strengthened.
