Corneliani Trend are definitely fused, and indeed I've even seen a Corneliani Linea Sartoria that was fused (even in the lapels!
, which was quite shocking to me since 99% of the LS line that I've seen have not only been fully canvassed, but made of superior fabrics. That said, this model is most likely canvassed -- all of the fused Cornelianis that I've seen are more fashion foward three button models. This is a classic suit. For $399, I'd say this is an excellent choice considering Sierras return policy.
