Calvin Klein closed New York Fashion Week with a hard-edged, no-nonsense collection that neatly encapsulates the pared-down aesthetic that is a key component for Fall.

It's a perfect moment for Klein, who clearly feels right at home designing austere, stylish basics with a mannish twist. In his hands, the most subtle details are all it takes to make a difference: His black wool winter coat, for example, comes with a built-in, low-slung double-loop leather belt that gives it a perfect air of nonchalant chic. A classic peacoat is cut loose and slouchy, as if to emphasize the slim proportions of a short, sexy shift. Klein's shearling dresses and aged, crackled napa vests, trousers and military coats are perfect for an urban warrior.

But even the toughest girls need lightness and femininity once in a while, so Klein also sent out plenty of body-skimming asymmetric silk jersey dresses with playful cutouts—just as long as you remember to wear them with tough ankle boots instead of conventional heels.
