Please tell me if my Dooney is fake?

I bought it off CL from someone on an "ok" part of town, by that I mean not rich but not poor, well off. She told me it was real, but I noticed the zipper pulls are silver and black and its a picture of a handbag with D&B on it and it says Dooney above the bag and below the bag it has Bourke. Has this on a leather tag that hangs from the handle aswell. It has a small leather tag below the inside zip. that has Dooney & Bourke. It also has the lil beige and red tag on the side with a smaller lil tag that says made in china. The style is all black, gym style bag. Let me know what you think, I never seen these type of D&B trademarks and I dont see a serial number..
