I'm currently liking Rimmel tan BUT am worried about wearing it on a day that it might rain.... does it not all wash off and run down your legs? Reason I ask is I was wearing it one hot day, when DD was in paddling pool with cousins and I had a funny mishap with the tap & hose when filling the pool....leaving my legs with big long white streaks and running with brown water. Thankfully the only company was kids and SIL so I could nip inside and fix the matter.....but what if I was out and it started raining heavily???? Anyone had this happen to them?
