I finally have a sports bra. Though I am so not convinced that it is fit for purpose. I bought one by Royce as they are one of few that cater to my cup size. The fit is quite firm though no wires. I felt like I needed a bit more than just one. My cousin had already told me she uses about 3 sports bras at the same time when she is at the gym as she does a lot of running. I feel as though I will need to use my regular wire bra underneath the sports bra when I start running on the treadmill for now I just walk.
So not completely convinced about the effectiveness of the sports bra. Though I will see how it copes with a round of Zumba.
