Chloe Kerala Here!

My boyfriend just bought me a Chloe Kerala as a gift, he says he bought it online as was guaranteed it was authentic. This is my first Chloe bag, the paddington didn't quite do it for me. Can anyone tell me what to look for or any tell tale signs it's a fake? The leather is really soft but I can't see a serial number anywhere, I love the style but feel weird carrying it around not kowing if it is authentic Chloe.
