I tend to wear mine in my bra too sugarfreerach as its out of the way but be warned it can backfire! I was in the middle of a consultation with a client at work(with pump safely nestled in bra as usual) when the low battery alarm went off! So my bra is vibrating and playing a little tune and I'm trying to ignore it until we're finished and the clients going 'whats that noise' anyway the noise is bad enough but the vibrating is really distracting, leaving me with little option but to apologise, explain its my insulin pump, turn around and extract it and turn the alarm off at which point I turn back-rather embarrased- to the client who is doubled over laughing shrieking "You've got musical tits!"
