While I can't wear this under all my clothes (believe me, I would if I could!), I did wear it to work today under a multi-colored top and it is fantastic! I bought this for when I cycle, and it's great then, too. I wear a 40-C bra and this worked for me, I don't think it would be enough support for really large breasted women. Very pleased with product and it shipped very fast!  :)
