DP92, have you considered that perhaps your personality and body type simply do not match the style you're going for? You seem like an athletic guy. Instead of trying to squeeze into these too-small, pseudo-businesswear items, why don't you take a look at some stylish, relaxed clothes? I know, for example, that adidas makes some very comfortable tracksuits; perhaps those would be to your liking?
I see lots of gentlemen with similar personalities, and they appear to enjoy this type of clothing. Many of them also have dogs. Actually, you could take note of these stylish gentlemen and add a thick gold chain, just to "spice up" your look. It would probably go well with your skin tone.
Something like this gentleman is wearing:
I would also suggest accessorizing with something that fits your persona. Perhaps an empty Big Boy of Carlsberg? Alternatively, you could forego clothes entirely now that it's almost spring! I suggest going shirtless, especially since you have the physique to back it up.
You didn't tell us you spoke British...
