2. Buttoning blazers incorrectly
Even with a well-made suit
, fastening the wrong number of buttons on your blazer can cause it to pull and stretch in awkward directions, making it seem ill-fitting, so pay attention to the advice that follows. Double-breasted jackets should nearly always be buttoned. With a two-button suit, fasten the top button and with a three-button suit, you have a choice between fastening the top two buttons or the middle one only. And no matter what kind of blazer you're wearing, always unbutton it when you sit down.
