The coveted spring 2007 Stella McCartney dress a silk, strapless A-line mini still, months later, haunts our dreams. And those Sergio Rossi stilettos? Dont even get us started. Its hard being a broke girl with a rich girls wants. But at LUXE, let the nightmares be gone. The well-appointed boutique recently has reopened its doors, this time on Marietta Street in of-the-moment West Midtown. Owner Jenn Ripley scours the land in search of recent seasons hot designs and sells them for 50 percent to 70 percent off retail. The above-mentioned dress, at $649, might not be cheap but compared with its original tag of $2,700, its a steal. And so be it if were a season off. We can rest easy knowing the fashion of our dreams really can come true.
