There are few items in a man’s wardrobe more stylish and classy than a three piece suit. The combination of jacket, trousers and waistcoat – worn with a nice shirt, tie and shoes – is something that simply looks superb, no matter the style of the suit or the occasion you are attending. Suits follow a few standard stylistic forms – single or double-breasted is one choice, and also the number of buttons – but there is one other decision that can make a difference.
