Thierry Hermes, the child of an innkeeper, went to Paris as an orphan, demonstrated that he was gifted in leatherwork, and opened a shop in 1837. Then, Hermes specialised in the making of horse harnesses required by high society and made his name by perfecting a stitch that will never become loose. This commitment to precision and quality has not wavered for almost two centuries and presides in all Hermes products, including ties. Usually the easiest way to spot a fake Hermes tie is to look for telltale signs of lack of quality.
Examine the silk. Shiny silks are often a sign of fake Hermes tie. The fact that all Hermes ties are carefully silk screened onto one of the finest silks available in the world means that there is an almost muted finish to the silk.
Flip the tie over and look at the colour of the interior lining. If it is black, it is almost definitely a fake. The lining should match exactly the background colour of the exterior tie.
Flip the tie over and examine the back of the wide end of the tie. Gently peel back the delicate folds and you should see a small loop made of thread around 1/2 inch to 1 inch. This loop will pierce through the silk of the tie. Hermes is the only designer in the world that does this, and the absence of such a stitch is a clear sign of a fake.
Check the tie stay on the back of the tie. You should see the Hermes logo, which is the horse and carriage. You shouldn't, however, see the words "Hermes Paris" under the horse and carriage. That is a clear sign of a fake.
Check the alphanumeric code which should be found five inches up from the bottom of the small end of the tie. The code should have three or four numbers which represent the pattern code, and two letters which denote the factory the tie was made in. Above the code you should see "Made in France" and below the code you should see "100% SOIE."
