Hey everyone, I know the models have been discussed before, but I spoke with a rep from Isaia and she typed out descriptions of all of the models from their marketing manual and emailed it to me. Hope this helps! "Sorry that it took so long to get back to you about the body types. Hope this answers all of your questions! Let me know if you need anything else! The Sirio ( S Body aka base S)- The most popular body within the Isaia line is also the fullest in structure The S Body is the base in the collection from which all others are derives. Defined by its classic Neapolitan natural shoulder, this garment was shortened slightly in 2008 to give it a more contemporary expression. This model as with all Isaia garments is available in 2 or 3 button, peak and notch lapels, single or double breasted. The Vesuvio (V body aka base V)- A tad more suppressed in the torso than the S body, these garments are defined by their rope shoulder, and even higher armhole. The Tribeca (T-Body aka base T)- The T body has a suppressed torso similar to the V-body. A lightly roped shoulder and very fitted sleeve- similar to that of a sweater. The Gregory (g-body)- Similar to the S body yet defined by a softer shoulder, this design carries a shorter body, and a mildly tapered sleeve. The Dustin Body (d- Body) This model has an even softer shoulder than the S Body, and even more natural deconstructed shoulder and is generally styled in a French face/half lined jacket. This shoulder shows "grinze" creases/pleating at the sleeve head. This soft jacket is usually accompanied by a 3 patch pocket. The X Body- Similar to the G body characterized by the single button closure which created a more fitted midsection with in the garment. ***** ***** 730 Fifth Avenue, #1004 New York, NY 10019"
