Leslie Jones made a fashion statement at the Knicks game Tuesday night -- wearing a shirt with the word "A-hole" written across the front ... while sitting courtside for all of the TV cameras to see!

As far as we know, there were no issues -- no one seemed to be bothered by the shirt ... including the TV crews who ran the risk of airing the uncensored word during the live broadcast.

The 'SNL' star had a great time -- she kicked it with NY Giants star Sterling Shepard and got high fives from a bunch of the players. Plus, the Knicks won!
