Well that is a three button suit. They of course lack the peak lapels and single button closure of the more common 'house cut' and are inherently more conservative and business-like as a result. There are two house cuts, or even three - the two listed on the website are one button, and three button, either with the option of peak or notch lapels (with pockets matched accordingly). There is also a house cut two button that you can see pics of on the blog, but is not on the website. The house cut really refers to the slimness of the jacket and lapels, and length of the jacket (ie shorter). It is offered on any type of suit TaT makes (one, two, or three button, and soon DB!) Conservative cut could be applied to any of the above suit combinations (except maybe the DB), for example, many people choose to widen the lapel or lengthen the jacket slightly - though it seems people who are most happy are those who have gone with the house cut. Am I right Jason?
