I own the square you're considering in a few colors. It's made with a very soft jacquard, foulard weight silk, which will give you a very "puffy" (for lack of a better word) appearance.
I worked for Hermes for a while, and the quality is very high, in my opinion. The COST however, is a bit much. As with many labels, you are probably paying 40% for product quality and 60% for a name.
That being said, Hermes makes some fantastic products, (I own a few leather accessories, ties, pocket squares and such). Hermes owns John Lobb (not the institutional, original bespoke shop in England, but they took over the Parisian Lobb workshop and store in the late 70's) so many of the men's shoes are made by Lobb. I'm actually not wild about the shoe styles though. If you want Lobb, buy Lobb.
All of the men's clothing is insanely over-priced. The outerwear/leather coats/jackets are made by Seraphin in Paris, and you'll pay a premium for the Hermes label. Suits/tailored clothing is made by Belvest and same there, inflated price for Hermes name. A super 190's suit from Belvest might normally run you $4,500, but at Hermes we're talking $7,000.
The leather goods are also VASTLY expensive. But, you are buying a completely hand made, (in many cases, hand-sewn also) product. They have several quality control stages and many products are rejected for the tiniest of imperfections. As a saddlery in the 1800's originally, they believe in the legacy of their leather craftsmanship and (hopefully) will remain committed to a high standard for years to come.
The ladie's scarves are the most popular product, next to the Birkin bag perhaps. They release hundreds of patterns in dozens of colors several times a year. No one does scarves like Hermes. All hand-printed in Lyon, one color at a time. For silk goods, (ties, scarves, squares, ascots papillions) you won't be disappointed.
Buying Hermes is a status thing. And be that as it may, I do love Hermes and if I was vastly wealthy, or at least better off, I would shop there more often. You can be assured if you buy something Hermes, it won't be crap.
