I purchased a Semantiks suit in-store at Nordstrom a couple of weeks ago while I was on vacation. I have been waiting for Nordstrom to put it on its website, but it doesn't look like what I purchased will be available online anytime soon. Unfortunately, the pictures I took with my iPhone aren't very crisp, but I really want to show the suit, because it's vegan and black and pinstriped, so an over-exposed picture is to the left.
The jacket and pants are made from a combination of rayon, polyester, and spandex. The suit is a matte black with small, very closely set, off-white pinstripes. See the pinstripes:
The jacket has two really useful pockets in the front and the pants have slit side pockets and fake back pockets (wish they were real -- the more pockets, the better). The jacket was $138 and the pants were $88, which totaled to a doable $226. I've worn the suit twice so far and absolutely love it. So comfortable! If you are near a Nordstrom, it's definitely worth checking it out if you are in the market for a black pinstripe vegan suit.
