I bought these rain boots at friperie Renaissance (a second hand store in Montreal). I paid only $7! Now my feet will stay warm and dry all winter!
I bought the coat about 5 years ago at Zara. The buttons felt down in the first two weeks. I tried to attach them many times, but they never stayed there for long :) Eventually I gave up; in fact I do not need them, because the coat has a zipper.
