This is the Oxa: a breath monitoring shirt or bra that teaches you how to breathe and gives you real-time feedback. It can measure your breathing rate, depth, HRV, and body temperature in real-time. Its companion app provides you with audio and visual cues to guide you through exercises.
Oxa comes with a sensor that connects to a shirt or bra. It is compatible with Google Fit, Strava, and Apple Health apps. This project is getting funded on Kickstarter. You can find out more about it here.
