AMI Alexandre Mattiussi Fit?
I personally only have a shirt, which decent--especially considering Mr. Porter's sale price. But based off that and the measurements on Mr. Porter it's all relatively slim but still TTS. Large usually equates to a 50, which is usually a 34-35" waist. The leg opening doesn't necessarily tell you how tight the rest of the shaft is, and from the couple pairs of chinos I've seen they're not cut super skinny.
