First of all, can someone explain the difference between a sport jacket and a blazer? Is there one?
I think "sports jacket" is a broad term for any casual 'odd jacket', as opposed to a suit or dinner jacket. And doesn't "blazer" typically denote a solid color? Â Most of the things I see called blazers are all one color and have metallic buttons. Â
Also, what's the consensus on wearing a sport jacket/blazer with something other than a dress shirt? What about plain t-shirts? polos?
Seems to me that a basic navy/black/neutral blazer is one of the most versatile items of clothing you could have...apart from the standard dress shirt and tie combo, you could wear it with a t-shirt, a polo shirt, a thin crewneck sweater, a v-neck with tee or collared shirt beneath, a turtleneck, an open-collar button-down, etc. Â I would think you could apply these rules judiciously to almost any sports jacket as long as you match colors/patterns/etc. I have a recent case in point: Took my wife to a 'rustic chic' sort of restaurant on Friday. I wore a charcoal 3-button blazer over a beige B-D oxford w/ camel+grey stripes, with an Italian silk scarf (mostly light steel blue w/ grey & beige designs) tied in a loose four-in-hand and tucked inside the open collar and shirt. Â This was over camel jeans and brown monk-straps. Â This drew several compliments, so I must have been doing something right. (Full disclosure: scarf borrowed from my wife's collection--guess that technically makes me a 'cross-dresser')
