'Vanderpump Rules' Star Danica Dow's Ex Avoids Charges for Slashing Wardrobe

"Vanderpump Rules" star Danica Dow's ex-BF -- the one she got a restraining order against -- is admitting he ransacked her wardrobe, but he's still avoiding criminal charges for the clothing attack.

So, here's the deal ... back in August, Danica got a temporary restraining order against Brett Willis claiming he broke into her home in the middle of the night, cut up a bunch of her clothes, and stole her iPhone.

Danica reported the incident to cops, but TMZ's learned the L.A. County D.A.'s Office will not file charges against Willis, and here's why.

We're told Brett copped to damaging Danica's clothes, but he offered to pay for damage and Danica accepted. He also returned her iPhone, which he said he grabbed by mistake because it looked like his. So, basically ... no blood, no foul so the D.A.'s Office decided not to charge him.

Brett tells TMZ ... he cooperated with law enforcement, and is relieved to close this chapter of his life. He wants to move forward with a positive attitude, but there's still the matter of a couple restraining orders.

Brett also filed for one against Danica, claiming she got violent with him in July over dirty dishes. He claimed she "grabbed my neck twice, each time digging her nails deep."
