This is the LOUIS VUITTON flagship store on Fifth Avenue with its colorful window display.
From the official website:
The 20-storey building is located at the corner of 57th St and 5th Avenue. The upper levels of the building are set back to create a monumental crystalline stalagmite, and multi-layered white glass wall reinforces this crystal-like form. The wall with its graduated transitions, from opaque to transparent, replaces the white marble façade at the lower levels and corners.
Since 1896, Louis Vuitton and its legendary gold monogram have been synonymous with luxury and timeless elegance. But while the line is best known for its durable, supple brown leather travel pieces, accessories and handbags, as well as the more colorful, artist-designed seasonal must-haves, one look inside the designer's flagship store, on 57th Street at Fifth Avenue—the largest in the world—reminds shoppers that Vuitton's style goes far beyond its carry-alls. Within the illuminated blue, white, purple and gold translucent glass walls are four floors—over 20,000 square feet—of classic men's and women's ready-to-wear, modern timepieces and jewelry, and uptown-chic footwear. Past the towering wooden grids that showcase the famed handbags lie the relaxed suits and ultra-feminine knee-length skirts that typify Vuitton's polished look, punctuated by bright colors and soft accents for a swank mix of tradition and modernity; this familiar style is echoed throughout Vuitton's designs, from the monogrammed canvas belts to the red ostrich-leather wrist watches. Black-suited sales associates are attentive, without being overbearing.
