Night time, I used the Hid-In belt wrapped twice around my thigh.
Day time, 8 usually clipped my pump to my waist band unless wearing a dress which, based on your picture, I expect you do even less often than I do.
Gym, I removed my pump as my cardio increased my insulin sensitivity so much I needed no basal.
Climbing (like weights and resistance training, raises my blood sugars), I clip my pump to my waist band. On one occasion, the clip failed but the pump remained attached and dangling. It disturbed my belayer more than me.
Flying trapeze (only tried once), Hid-In belt as a belt under my clothes to keep it out of the way of harness and avoid pump flying whilst doing a summersault.
