I love this bra. I usually don’t like sports bras without padding and with skinny straps for running - I just don’t feel supported enough - but this is totally different! The double layer of fabric and tight supportive band (which is admittedly a little difficult to take off) make me plenty comfortable running in this! Plus - it is wear all day comfy - nothing digging into your rib cage or shoulders! For reference I’m a 32 C/D and got a small.
