Kris Humphries Sued -- Accused Of Ripping Off Bev Hills Suit Shop

Kris Humphries swindled a Bev Hills suit shop out of thousands of dollars in designer threads ... by promising to deliver NBA clients in exchange for a discount ... this according to a new lawsuit.

K.H. is being sued by Scott Hill -- who claims he was approached by Kris and Kim Kardashian a few years ago in the hopes he would provide clothes for Kris.

According to the lawsuit, Hill says he struck an interesting deal with Kris -- I'll give you a 30% discount on clothes if you introduce me to at least 2 of your NBA player friends to my store within 12 months.

Hill says the NBA players didn't even have to buy anything -- he just wanted an intro. Easy enough, right?

According to Hill's suit, Kris agreed to the deal ... and proceeded to buy more than $46k in merchandise using his massive discount.

Problem is ... Hill claims Kris not only failed to deliver on his end of the bargain ... but he still owes more than $6k in unpaid suit bills.
