I forget now who produces them, but it isn't a very famous maker (certainly not a suit maker). Most are made in Morocco. The quality and fabrics are so-so but most buy them for the cut/style. As well, compared to most designer suits at retail, they are priced more reasonably. Generally, they run perhaps $1200 or so. So, I don't think you'll get much handwork and all the ones I've seen have been fused.
All around, still a fair suit, but purchased more for the style than for the quality. If you could get one for less than $400, I'd say it would be worth it, unless you just love Dries' style. If you are searching for high quality at that price point, you can find better elsewhere.
