There were a lot of scenes where characters, generally including T'Pol, would get "decontaminated" which meant rubbing each other down in their underwear.
Enterprise was just a hornier show in general. There was that one episode where the crew were locked in their rooms (I think the Ferengi happened?) and Hoshi had to crawl through a vent, and she fell out of the vent and this somehow tore her shirt off so Malcolm opens the door to find her topless. Why did that have to happen? Geordi LaForge and Data didn't get shirtless anywhere near as often as Trip Tucker and Malcolm Reed do.
There's only one episode where they stretch the scene for an uncomfortable amount of time and have her and Trip really rub each other (as far as I remember).
I don't know, would you rather spend 4 entire years in bone tight fetish outfits too tight to sit down in and 4 inch heels, or 4 years in a relatively sensible jumpsuit or a jacket/pants ensemble but you have to peel to your undies and share a bottle of baby oil with a male castmate for 3 minutes?
This is the outfit in question, which strikes me as more modest than any of Troi's various jumpsuits. The neckline is less open, the material is more substantial, and it doesn't really seem to fit much tighter than average women's clothing. I don't believe this outfit has a built-in corset the way Seven's catsuits did. I'm speaking as a man, here: If you gave me the choice between Seven's or T'Pol's costume, I'd choose T'Pol's. I'd look hilariously stupid in both but I think T'Pols suit would hurt less.
