raincoat woes

There seems to be a blip in the universe when it comes to me finding the perfect raincoat. I had a perfectly adequate beige raincoat that had traveled to several countries with me but it was stolen with my suitcase in Seattle last May.  Before my summer trip to the British Isles I bought a supposed rain coat at the mall.  You do need a raincoat in Scotland in July.  Unfortunately it turned out that raincoat wasn't waterproof - cute but not waterproof - which pretty much defeats the purpose.  Now I am about to leave on another trip, this time to a much sunnier place, but the detailed instructions from the travel agency said to bring a raincoat.  So I went shopping again. I found a beautiful turquoise rain jacket at Kohl's clearly marked 'waterproof' in my size. I bought it Friday and brought it home. Yesterday when I started to cut the tags off I discovered that the security tab was still securely attached. I have no idea how I managed to walk out of the store without setting off the alarm.  Today I took the coat back, clearly set off the alarm as I walked in and got the tab removed. So now I have a legally owned, untagged raincoat, hopefully really waterproof, and I really, really hope I don't need it at all on this trip.
