An American-Style Suit is best for larger bodies and was first created o accomodate the larger frames of many Americans compared to their European counterparts. Two classic suits that still make it appropriate for today's larger men are the three-button, single-breasted blazer and the plain-front trousers. A three-button blazer, like a two-button blazer, will never go out of style; however, the three-button blazer, particularly when the top button is left undone, has the advantage of elongating the body of a heavy-set man, thereby making him appear taller and thinner.

The Two-Button Suit
British Suit:
English suits are most flattering on average and athletic body types. British suits tend to confer an authoritative appearance on their wearer. Like a uniform, the shape of the suit also follows the line of the body quite closely and puts emphasis on the chest. Other features of English-style suits include soft shoulders and slightly shorter jacket sleeves. Men with very V-shaped, athletic bodies will benefit from a single-breasted, two-button blazer in which the lapels sit higher up on the chest in order to reduce emphasis on the width of the shoulders. The nipped-in waist of the British suit, as well as its tapered sleeves, are also good for athletic bodies as these features emphasize other areas of your body and take attention off your top half.
Continental Suit:
The traditional aspects of Italian suits have been a close cut, severe shoulders, a shorter length, and small, high armholes. Also, these suits are usually single-breasted with two buttons, have slim-cut trousers with a lower rise and a ventless back to slim the figure further.
