Judge to Danielle Staub -- No One Can MAKE You Strip!

Danielle Staub can keep her pants on ... for now ... 'cause the former "Real Housewives" villain just won a nasty legal fight with one of the biggest strip clubs in the country.

TMZ has learned ... a federal judge in NY just ruled that Scores New York failed to show why Staub had a legal obligation to continue working for the gentlemen's club after taking a $25k payment to perform in a stripper video in 2010.

As we previously reported, Scores sued Staub for $375k ... claiming she failed to make a series of appearances at the club and on the Scores website ... after accepting the initial payment.

But in the court ruling, obtained by TMZ, the judge claimed Scores drew up a "vague" contract ... and never clearly specified Staub's obligations to the club.

The judge officially dismissed the lawsuit Wednesday -- but the war may not be over ... 'cause Scores can bring the fight back to the court if new information comes to light.
