I'm wearing it with my Lululemon Arise bra in camo (which I totally forgot I had!), and it's nearly perfect. Even a Flow Y bra works though, or any other bras I suppose, if you don't mind straps showing. Sometimes when the strap designs are really pretty, like in the Energy bra or the Centered Energy bra, you probably want to show off the straps anyway!
So happy about this tank! It's awesome to finally get something that I've been wanting for a while, so yay!
