Hi. I'm not an authenticator but faced with a similar situation here is what I found out:
1) authentic Kate spade logos will be written as following:
kate spade
NEW YORK
the N will be aligned with the t
The K will be aligned with the a
The logo patch inside should be slightly embossed and stitched into the bag. You'll be able to peel fake logos off
The logo outside the bag can be embossed into the leather but I've noticed the outlet bags seem to come with a metal tag on the outside (which again should not be able to pull off easily). I also saw bags at
Nordstrom rack like this. But I don't think it's any sort of rule. I noticed many guides suggested the metal tags indicated a fake but I saw authentic bags with them. Some bags also have the logo in metal on the outside of the bag with the spade above.
2) there should be a serial number inside the bag. I'm not sure of the format but I believe it should begin with the style number. It seems that outlet and final sale bags begin with wkru style numbers. You might be able to call KS customer service say the bag was a gift and have them verify the serial number, though I'm not sure they do this.
3) the bag tag is different than what I've seen. I read "our price" means the bag is an outlet bag. The different font and CAN price might mean the bag was made for Canada - not sure about this though.
4) look at photos on TPF where people post their brand new KS bags from the store and compare the features of the authentic bags to yours.
5) I think it's possible for there to be counterfeit tags with an authentic bag and vice versa if you are buying the bag second hand.
Good luck! I hope these things help. Authenticators if I've said something incorrect please correct me.
