Light Support Strappy Sports Bra Because I have a smaller bust and don't need much support, this Light Support Strappy Sports Bra ($15, originally $20) is my favourite. It's lightweight and comfortable design is exactly what I need for low intensity workouts. Plus, it comes in several colours and I love the cute back design.
