“It’s my story,” noted Isabel Marant, preshow. “A woman who lives life every day and needs to be comfortable.” And, yes, fall was absolutely that, except this time the designer dished out her signature brand of nonchalance, Wild West-style. The combo worked — to a degree. Her borrowed-from-the-boys sensibility offered a new angle on the season’s outerwear trend — coats came nicely oversized, whether mannish or ruggedly cut from thick sheepskin. Patchworking? Marant chicly tackled that theme, too, in the spliced denim series of shirts, vests and jeans. Her Native American riffs, meanwhile, were best in the watercolor feather prints on casual basics (slouchy sweatshirts and Ts) and the seemingly inside-out Navajo-pattern knits rendered slightly undone with loose, trailing strands. But that fringe motif didn’t work so well when it came to everything else. Marant had the stringy stuff cascading down suede tunics, tight-knit dresses and on the side of slouchy boots. It was too literal a gimmick and only boosted the somewhat haphazard vibe throughout.
