I am not well suited.

• Double breasted or single breasted ?
• Two buttons or three ?
• One vent in the back, or two side vents ?
• When can a suit's jacket be used without a matching pant, to give a semi formal image ?
• What is the difference between a suit (it's jacket, that is), sports coat and a blazer ? When can they be used interchangeably ?

I am obviously not well suited for this kind of thing yet ! Soyouwanna says:
Take our advice: stick to jeans and T-shirts. Leave suits to lawyers (get it? "law suits"?). Ya ya, I know.
