I know I said I wasn’t out to convert someone, but @Mike,
Bra – in the middle, just like @Alison said. But underwires don’t seem that keen on the idea – 2 bras needed stitching in 3 months of pump wearing. The only ‘dress’ problem I’ve encounted is when I have to get my strong pants out in order to wear said dress, and this puts a wee bit of pressure on my infusion set. Nothing too untoward though….
