The real problem is when GQ starts hawking tight tailored clothing under the pretense of slimness:

That slideshow shows:
1)a jacket with crazy tightness lines at the waist
2)trousers with tightness in the crotch and pockets flaring out
3)another absurdly tight jacket and trousers
5)the tightest trousers yet. Note also comically short jacket.
Throughout, sleeves are consistently wrinkled from tightness. Remember that this is an unnaturally thin male model--if this clothing is tight on him, who is it made for?
Thus, even if the slim-fit trend has its advantages for those of us who know what we're doing, it will inevitably have bad results in the form of men who think tightness=cool.
