It's been a banner year. Michelle Obama wore one of Barbara Tfank's box-pleat dresses in May—"She loves my florals," the designer confided—and celebrities from Adele to Vanessa Redgrave are being snapped in the brand. Feeling justifiably upbeat, Tfank worked an exuberant pastel palette for Spring. A few darker hues showed up, too, but even a black dress chez Tfank can never look moody: The tailoring is too crisp and the styling too fresh, and everything is always coming up roses. The lovely sunburst print on a tight-bodiced A-line number (with a full skirt and wide, collarbone-revealing neckline) was shot through with gold. An adorable high-waisted black cotton skirt with oversize pockets and buttons running down the front was shown with a little white tricot bandeau, but the midriff revealed was extremely minimal, so it maintained an air of innocence. The real head-turner, though, was a gathered floor-length V-neck dress in a graphic black-and-white print. Upon closer examination, it was revealed that what looked like geometric abstractions were actually a bird's-eye view of topiary along a garden path.
