A person/object who is very fake/false/misleading is just like a fake wanna-be-brand-name bag sold for dirt
cheap on the famous Canal Street in New
York City: appears to be the real thing instead it will
break apart on you in the middle of the street when you count on it the most.
Oh please I knew she was a liar, she's as fake as a Fendi on Canal
Street!
or
That is definitely a
knock-off, can't you see it's as fake as a Fendi on Canal
Street?
or
With that Fendi on Canal Street of a girlfriend he has, I wouldn't be surprised if he took her out of his will!
