Collage is a recurring theme in Julian Louie's work, and this season he turned exclusively to piecework. A dress in silk tassar—more grain and less sheen than regular silk—had a color-blocked top and a pleated taffeta skirt in bands of contrasting shades. With its dropped waist emphasized by the shift in fabrics and colors, it looked a bit like a very awesome tennis dress. Lush florals were another part of the story, and Louie developed his prints by manipulating photos he'd taken at the Brooklyn Botanic Garden. Sure, they'd been Photoshopped, but you wouldn't think something so wild could grow in the metropolis. Spliced up and patched in next to one another, the grasses and magnified petals had a palpable energy; they looked ready to burst out of the linear shifts and T-shirt dresses Louie had contained them in. Cloglike wedges (not suitable for gardening), some in the same floral print, were the result of another collaboration with Aldo; if they prove as popular as last Spring's ikat wedges, we imagine both designer and shoe retailer will be pleased. And for Louie's customer? There are standout dresses and cool separates here to make her happy. Though similar, each of these 15 looks packs a pretty punch.
