Nothing says luxury like limited edition. From fragrance to footwear, designers are upping the ante with exclusive offerings. Look for Diesel Fuel for Life, two new fragrances packaged in refillable waist-worn chains ($75) in brushed metal and gold. The women's scent has notes of jasmine, patchouli, black currant and crème de cassis, while the version for men packs a punch of raspberry. Dolce & Gabbana's men's sneakers ($575) made with lamé and patent leather pairs luxury and sport. With just 5,000 pairs available worldwide, the sneakers come with a unique number stamped on the heel for the ultimate in exclusivity.
