Spring’s premature arrival has inspired a feverish desire among clotheshorses to rotate their winter wardrobes early, and a new crop of stores are heeding the call. Aussie swimwear label Zimmermann unveils its first New York boutique on Wednesday, showcasing bandeau bikinis and pinup-style one-pieces against a beach-glass-green interior (87 Mercer St., nr. Spring St.; 212-226-6440). Canadian trend-chaser Joe Fresh opens a 14,000-square-foot flagship—its largest to date—on Friday, packed with maxi-skirts, color-blocked dresses, and a beauty line (510 Fifth Ave., nr. 43rd St.; 212-764-1730). British shoe brand L.K. Bennett, maker of Kate Middleton’s wedge of choice, launches Sunday at Time Warner Center (10 Columbus Cir., at 59th St., second fl.; 212-309-7559). On the menswear side, Brooklyn’s brother-designed Feltraiger is bringing its sharp button-downs and cheeky tees to the Lower East Side (158 Allen St., nr. Rivington St.; 646-397-8136), while Italian tailor Cesare Attolini fêtes its first haberdashery outside Italy on April 3, offering ready-made and custom suits north of $5,000 (798 Madison Ave., nr. 67th St.; 646-707-3006).
