How can I spot a fake perfume which is New in Box sold on eBay?

I just bought a NIB (new in box) Ralph Lauren Romance for women perfume (3.4 fl. oz) and trying to figure out if it is real or fake. If anyone have one of these, could you please check what it says at the back and whether there is a barcode both at the bottom and the side? Please help me spot a fake!

You could always take to a Retailer or Trading Standards and get verified
