I thought this is a great concept, bra and tank in one. The tough part is figuring out the correct size. I read all the reviews. So it seems the major consensus is that the tank runs TTS but the built in bra runs big. According to CRZ size chart I should between their Small and Medium. I have several of the CRZ sports bras, and those sizes run all over. So I took an educated guess at a size Small and luckily that was it. I got the blue tank with the black bra combo. Love it, worn it the next day and received many compliments. For reference I’m 34C, 133 lbs, normally wear size XS to Small tops in the mainstream brands. My only wish is that they bring back more in stock in different colors so I can buy more.
