I love the fit! You and Claghorn are the reason why I'm having my old three button suit worked on at my tailor. My first suit that I ever bought for college, and its been laying dormant in the back of my closet for over 8 years and I just found after doing some spring cleaning of my closet. Thanks for the inspiration TTO. Ill post some pics when I get it back from the tailor. Its the only 3 button that I own (or atleast I could find) and just did not have a lot of inspiration to wear it.
