Incomparable

Way back in the early 90s, the incomparable Monica Fraga was considered one of the most beautiful models in all of Latin America. During this classic guest appearance on (I think) Ney Gonçalves Dias, the former Brazilian Playmate agreed to take part in a body painting demonstration, which - naturally enough - required that she strip down to her lingerie before a studio audience.

As far as I can tell, Ney Gonçalves Dias - ostensibly a 'news & views' program - featured regular stripteases by well-know female celebrities. During the show's closing credits, the girls would dance before the cameras in their bare knickers, apparently their sole reason for being on the show in the first place. I managed to dig up a few examples on youtube; unfortunately, the resolution leaves a little to be desired (some of the VHS sources are nearly thirty years old).

Very grainy, but watch until end credits.

Extremely low res; sorry...

Baile de la seducción

The time-honored Latin tradition of Baile de la seducción (Dance of Seduction) has a history dating back well over a century, originating in the portside taverns of Argentina and Uruguay. Traditionally, the dance was performed by mixed couples seeking to express their unabashed devotion for one another (the Tango being a prime example), but fortunately for us, the Baile is now more often the provenance of hot young girls in their underwear.

Ecuadorian variety show Vamos Con Todo featured a plethora of models voguing in their designer lingerie, as was the case with Kathryn Arbenz (see above) shedding her inhibitions to the tune of Mancini's Pink Panther. Judging by this clip, the show's female guests loved modeling their intimates in front of the camera.

Interesting side note: at the end of her number, Ms Arbenz was offered a satin robe to cover her modesty. For some inexplicable reason, the crowd strenuously objected to this gratuitous concealing of the underwear, chanting "ROPA! ROPA!" at the top of their lungs. Duly impressed by the crowd's obvious enthusiasm, Kathryn capitulated to their demands, apparently spending the rest of the episode in her bra and panties. 

Legendários

 Spanish variety shows never fail to deliver the goods! In this apparently "improvised" sketch, four beautiful Galician women strip down to their bras and panties to model their lingerie before a live audience:

From what I can gather, this seems to have been a regular segment on Legendários, as suggested by this youtube video:
