Telling if your hat is fake or authentic is NOT a simple matter that most website and blogs would make it out to be. Some common misconceptions would be to look at the stickers/tags/labels on a hat. No you can't just look at the poor embroidery or a misplaced tag. No matter how many picture examples you see on google or videos you watch on youtube to identify a fake hat, your answer will not be concrete. I dare any hat expert to identify whether a hat is fake or not over the phone with a layman–it's just not that simple. Unless the appraiser of the the hat has a questionable hat in their hands, it's truly difficulty to identify a fake hat. An example of this would to compare it to identifying if a $100 bill is fake or not just by watching a few videos or comparing photos. The reason for this is hats are not made the same every single year and some years has it's own quarks. So you might compare a questionable hat against some information that is way outside of the hat's production era.
Sooooo what's the solution? Here are some:
1. Don't buy your hat from any 3rd party seller (e.g. eBay, Amazon, etsy) or from countries that are notorious for producing counterfeits (e.g. China). In other words, don't question your hat's authenticity when you bought it through an already questionable source.
2. If you're unfortunate enough to have a hat in your possession, take it to your local hat store to have some employees look at it. Now I'm not saying their answer is gold but they're more than likely able to tell if a hat is fake of the strength of them handling 1000's of hats before. In other words, I would take their word any day over the person online telling you about all the tips and things to look for in a fake or authentic hat.
This leaves you thinking...dawg you didn't even answer the question. My response would be that it's just not that simple and every hat needs to be looked at on a case by case basis and no tips or pictures will be enough to cover EVERY hat out there.
We made a video about this...enjoy.
