How do you tell an authentic gucci hat?

First of all, the signature colours (green/red/green, blue/red/blue...) will be located near the bottom of both sides of the cap, the colours start about 2.5cm away from the end of the hood and leaves about 2cm gap at the end to where the hoop and loop closure is located (at the back). The colours would be bold and the material should feel rich, real leather strap which has no tex at the side with the spiky attachment to the velcro and at the back of the leather strap will have a serial code on it.
