There are many accessories that let you keep the pump concealed. For women, a popular option is a bra pouch. It clips on the side of the bra and the pump hangs under the arm. This insulin pump pouch works well for formal dresses, sundresses and tank tops. There are also specially designed thigh and arm pouches. Some women just put the pump in a baby sock and tuck it into the front or side of the bra, or pin it under their clothing.
