My favourite ones are the lilac zip ups from Joules.
Do you wear rain boots? I've had some polka dotted ones for about 6 years. I bought them in Winnipeg where it never really rains that much. The boots were cute and on sale and I was happy to trade my Sorels for wellies when I moved to Sacramento. The backyard of my first house in Sacramento had a dip in it and would flood every winter so the boots got a lot of use during the rainy season. I haven't pulled them out yet this year mainly because I've been trying to stay warm and dry inside (and also figuring out how to make these idea boards using GIMP.)
