Jesus, I'm glad none of you pick out my clothes for me. I'd look like an idiot with some of these styles and I'd be constantly uncomfortable.
Well, you do have to have the sense to pick out styles that go with your own body type. General tips on fit and fabric apply across styles. No matter what your style and body type, you want the clothes you choose to fit properly. For men, the simplest part of fit to consider, and the most common one that they ignore, is the shoulder (it's important for women too, just women seem better at getting this part right). It doesn't matter if you like t-shirts, polo shirts, button-down oxfords, dress shirts, suit jackets, smoking jackets, sweaters, sweatshirts, neutral colors, bold colors, pastel colors, solids, stripes, random blotches, etc., if you make sure the shoulder fits right, it'll immediately look better on you than if the shoulder is too big.
And with pants, just try the darn things on before buying! I've known so many guys who know their waist and inseam size and just buy anything without trying it on. Not all pants are cut equally, and not all look equally flattering on everyone. Some guys should wear flat front trousers, others are better served by pleated fronts. Some need a little more room in the seat to show off their cute butts, others should get something slimmer so there isn't a lot of bagginess to accentuate their lack of butt. If you have skinny little chicken legs like that model probably has, slender pants will look best. If you have ginormous thighs from working out, a looser fit would be in order (though, those guys usually need to buy a couple sizes too big to fit their thighs, then have the waist tailored smaller). You have to think about what flatters your body type. There is no "ideal" body type. Everyone can look fantastic if they choose clothes that suit their type.
