The Hong Kong Observatory is predicting a 10-degree drop in temperature this week - but fortunately CitySeen has discovered the perfect way to keep your vitals toasty. Triumph's Bio Energy Cosmetic Bra promises to heat up your assets by at least 1 degree Celsius, thanks to the hi-tech 'Masonic N Fibre'. It contains microscopic ceramic particles that stimulate blood circulation in the breasts and allows it to 'emit 8 per cent more high-spectrum infrared rays than normal fabric'. The bra lining also has moisturising properties with ingredients such as aloe vera and algae. Triumph's spokesman admits you can't feel or see any substantial difference, but 'we market the products based on comfort and sensuality, not scientific results'. Confused? You see, the warming Kanebo fabric is so hi-tech that the wearer can't actually feel it. Truly amazing.
