At BCBG Max Azria, designing couple Max and Lubov built their Fall collection around the bold geometric abstraction of constructivism. Logically, shapes were of clear importance, both with respect to silhouette, as in the volume of blouson coats; and to construction, in, say, the sleek panels of velvet and silk pieced together on dresses. With robotic-looking metallic tights, bands of trapunto stitching, and jutting sharp lines on shoulders, the effect was often a bit "beam me up," even with mitigating crafty touches of shibori tie-dye and pleating. Things did loosen up a touch with a group of slinky little jersey dresses, high-necked in front, sexy and skin-revealing from behind, but overall, this collection skewed too serious for a line that's billed as a contemporary younger-sister brand. Perhaps it's because the Azrias' newest line, BCBGeneration—an even more casual (and less expensive) addition to the stable—is now a year old, making this label the middle child. Still, that probably doesn't change the fact that the BCBG girl—like Lily Collins, Amanda Bynes, Joy Lauren, and the rest of the starlet-stocked front row—doesn't really want to think too hard about the future when she goes out. She still just wants to have fun.
