Love this bra! As a 34DD gym girlie, it can be tricky and stressful finding cute, comfortable, but also functional sports bras. This one fits me perfectly, so I’d say the size chart is accurate and that the bra is TTS. While I definitely wouldn’t recommend running in this, all other light cardio is so secure and comfy in this. Also any weightlifting, yoga, stretching, etc. For any other larger-chested ladies, just be mindful this can be a little lower cut on the chest, so if that bothers you, you may want to skip.
