Even though Veronica looks voluptuous in her outfit, she still comes across as sincere and forthright. The cleavage is appreciated but I think the plain brown soft leather gives her an honest touch. For example, if it were black leather then it would give off a totally different look. 

The soft brown leather is a dichotomy of meaning.  One point that you made that I thought was interesting was her unique fashion choice - not really conforming to anything on the plateau. That helps reinforce the independence -- and unfortunately the loneliness -- of Veronica.  The soft brown leather shows that she hasn't grown up as a sophisticated adult, yet Veronica is able to kill dinosaurs to continue her survival; for her, it's just another day on the plateau.  Again, the loneliness: Veronica versus the rest of the plateau.  The soft brown leather also accentuates her sexy allure, incredible good looks, and well-tanned, sheened hard body ... constantly dripping in excess from the heat of the jungle.

Comparing Veronica to Marguerite, I noticed that Marguerite's style is lacier, fancier. This fits the characters persona well. Veronica's look fits her character: simple, straightforward, but with a touch of elegance in the cut of her outfit. Marguerite's look also fits her: lacy, fancy and extravagant -- also a wonderful cut -- but not so straightforward.

For Marguerite's sake she should start dressing in more jungle-like attire. Marguerite is a very mysterious and mischievous lady, and if Marguerite wore a more deep and sexy plunging outfit, the mystery would only deepen.  In a psychological sense, the mystery ... the heat ... associated with her character would intensify. However, Marguerite should always wear some type of medallion, or some white undergarment, particularly well hidden, to symbolically ... slyly ... show the goodness hidden underneath.

They have both been on the plateau for years and who knows how many more years they WILL continue to interact with the creatures on the plateau.  I would expect both to influence each other's clothing such that both would converge on plunging tops and short shorts, but with a subtle touch of European extravagance.
