@Tim I’m sure your diabetes control would benefit from you wearing a bra. I believe red lace is meant to be best for lowering HbAlc.
@Annette I clip mine at the front in the middle, so the clip goes over the bottom bit of the bra and the pump hangs down. In most dresses you really can’t see it. I’ll stop there, I’m not doing a very good job at explaining it and I’ll get myself into trouble soon! I know some people wear them at the side underneath their armpit but I found that really uncomfy.
