hi there...have had an impossible time trying to find a plastic underwire bra or a really really supportive non wired bra. I work in a secure environment and keep setting of the security alarms...the only metal i have on me is the underwired bra! gah! i ordered a non wired one from M&S but it doesnt last the day and my boobs end up dragging on the floor!!! ok a slight exageration but has any of you larger boobied ladies had any success with obtaining a plastic (or just non metal) underwired bra? or a support non wired one...
