Breaking News: Y-3 Boutique-in-Boutique Coming to Joan Shepp

Philadelphians, rejoice! This is seriously cool.   

There are currently three Y-3 boutiques in the world — each of them a shop-within-a-shop concept — in Berlin, Tokyo and Paris. By the end of August, there will be a fourth outpost of the line — designer Yohji Yamamoto’s luxe-meets-functional, tailored-meets-sporty couture collaboration with Adidas — landing in this country; in this city. And it’s landing on the 600-square-foot mezzanine inside Joan Shepp’s eponymous boutique, right here on Walnut Street.

Obviously, we’ll be bringing you a report as soon as the ribbon’s cut, but until then, you can dream about one day having to go no farther than Center City to shop the entire — both men’s and women’s styles — fall/winter 2009 Y3 line. Expect clothes that play with the themes of movement and expression, with sharp silhouettes and rich winter fabrics, all in the line’s signature, minimalist black-and-white palette. I, for one, am waiting with breath that is baited. And ready to shop. (Psst: To help make room for all these changes, the store is having a Renovation Sale right now — all designer merch is marked down, both in-store and on the website, by 50 percent.)
