Wearable devices are in fashion. Don't believe it yet? Just ask Victoria's Secret. The famous lingerie retailer has just outed, albeit without much fuss or fanfare, a new bra named "Incredible" that incredibly has its own heart-rate sensor inside. Designed for athletes and women with active lifestyles, this bra will allow users to be updated of their heart's status without having to wear conspicuous or uncomfortable straps. That said, you'll still need to wear or at least attach some monitor of sorts to go with it.
