There's been some discussion about this brand, including a breakdown of each line. Click here to read it.
Here's my two cents: I have a Cerruti 1881 sport coat that I love: three button, no vents, with patch pockets. It's cream colored wool that is so soft I'm almost convinced it's cashmere. The jacket just drapes beautifully on my frame. It is a bit full cut, and fits me much as a Zegna would. I really can't say enough about the fabric. Given the popularity of the movie American Psycho in this forum, there's another point worth mentioning. That is, the suits worn by everyone in the film (read: Christian Bale, Josh Lucas, etc.) were custom made by Cerruti. Clearly, the fact that they're bespoke makes them look great, but the construction and materials are clearly beautiful as well. I would highly recommend the brand, with the exception of the Nino Cerruti line (as someone once said, fused front dross).
