I dunno, man. You look at Raf and Jil from a few years back and their dress pants are already super skinny. Look at Ovadia and MB for current seasons featuring super tapered/skinny office attire.
Ovadia, MB and the like are EXACTLY what I'm talking about. Right now, the majority of the men wearing these pants actually fit in them, but the bulging thighs are starting to creep onto the landscape.
