I agree with most of your analysis except for her outfits. Every other woman on the ship wears a standard uniform, no other woman on the ship is vaguely sexualized. We have plenty of opportunity to see that women aren’t just ditzy accessories for men but equals.

It feels weirdly regressive that there can’t be a woman with cleavage on the show else it’s sexist and reductive. Obviously women aren’t just there to be sexualized by men, but some women enjoy it and that’s okay too. Basically you’re slut shaming Deanna.
