Currently, at work, I use a padded bralette with removable option. I then add pads, sometimes i need to cut them to fit, and now I have hust over an a cup under a babydoll tshirt... I'm more than sure coworkers notice. For the weekend I use a water bra with a b cup and supplement with a foam insert, really inexpensive at a lingerie store or ebay. Good luck! Have fun!
