I have one of his jackets. It's black - rayon I think, but yeah, the texture is really incredible as is the design. It's fairly conservative, but is different from your typical suit in subtle ways that make it stand out. The cut is perfect right off teh rack (got lucky I guess). It's a three-button design, but instead of buttons, it has brushed aluminum twist-lock snaps and the sleeve has about a two inch cut from teh cuff instead of buttons.
I wore it to my boss's Christmas party with Guess 'Lincoln' jeans (black), black Kenneth Cole dress boots, and a white slim fit Express shirt. I was getting compliments all night on how sharp I looked.
I just happened to find this jacket on a trip to Vegas and it was listed at around $1,900, but talked them down to $1,700 (whatever, I would've paid the $1,900 anyway - it looked that good).
