ENTERPRISE making Jolene Blalock take her top off to get ratings. I do not recall any other STAR TREK series desperate enough to go to those lengths, just to get someone to tune in and watch.
Doesn't TNG: A Matter of Perspective open with Picard working on a painting with a nude model?
TNG showed that Ferengi transporters remove the clothes from women.
Betazoid weddings are performed naked, as Lwaxana frequently was fond of reminding everyone.
VOY had Q Jr. ogling a nude Seven. Janeway stripped as well, I think it's in "Sacred Ground".
The worst about the topless scenes is that they weren't done in any way that was sexy, or even artistic, in any way. She's just there, arms crossed, with a hand over each boob, whilst holding a conversation. It was just lame. I am all for having STAR TREK women flaunt it, if they got it, but ...
Nah. The worst about the T'Pol topless scenes is she was usually facing away from us.

Hoshi had her top torn off too.
