If you wear a suit it can be awful or incredibly sexy! If the jacket fits your shoulders/ arm length/ and does stop below/before the hip and the buttons do not pull then you have the perfect suit jacket. with the pants..don't let them drag! and the inseam needs to be taken properly.
As for everyday wear. I like undershirt with a button up over top with a few top buttons undone. ALWAYS wear and undershirt. Roll (as in fold make it look neat and put together!) the selves so they are 3/4 long (stop below your elbow) if you have a shorter torso tuck the shirt in and add a nice belt. if you have a long torso leave the shirt out and no belt. A belt is a accent piece it really should not be holding your pants up. Buy pants that fit. with the button up shirt a pair of dark jeans unless the shirt is very dark then go for a medium wash jean.
Also a nice sweater most likely NOT a cardigan over a button up is hot. And once you get that nice suit jacket if it is plain black you can pair it with nice jeans and a basic shirt.
So if the suit fits well. I find them incredibly attractive.
