Nah.

I mean, yes, in the TNG era it was Rick Berman's fault. But it goes all the way back to TOS and Gene Roddenberry himself. And also costume designer William Ware Theiss, for that matter.

From https://tvtropes.org/pmwiki/pmwiki.php/Main/TheissTitillationTheory :

Though Theiss was a costume designer, according to Inside Star Trek: The Real Story by Herb Solow and Robert Justman, most of the costumes — following this theory — were actually somewhat more modest before being "improved" by Gene Roddenberry. According to the "Art of Star Trek" book, Theiss preferred to design costumes that only appeared to be in danger of slipping or coming off, through the use of strategically-placed sheer or skin tone fabric. He was further able to enhance the effect by the censorship rules of the time regarding what parts of the body could or could not be shown (the navel being the most well-known restriction). He found he could get surprising amounts of appeal from the carefully-arranged display of skin not generally considered erogenous.
