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.

At least Blalock didn’t faint because her costume prevented her from breathing
