Joanna Krupa Wears No Bra Under See-Through Dress While Talking Trump

Joanna Krupa has a way of making politics very titillating ... and it involves wearing a see-through dress. Without a bra.

The newly single, ex-'Real Housewife' was leaving Craig's Wednesday in WeHo -- and while she waited for her ride, she got to talking Trump and how politics break up couples.

We'd like to say this is an interesting convo because Joanna just separated from her husband -- but we'll be honest ... she's damn near naked.

So, enough talk. Watch the clip.
