My daughter has had zara coats for the last two years in a row. I can't resist them, they are so cute and stylish. I have gone for practical water proof parka style ones with fur trim hoods both times.
They are great quality, nice and warm and wash well, but I find the zippers are poorly designed and seem to catch and get stuck on overhanging seams if you are not very careful about the way you zip up (if that makes sense). You then spend an eternity trying to unjam the thing. On several occasions, I have had to peel my daughter out of a partially zipped up coat and then work on releasing it. Last year, the zipper got so jammed right at the end of our extended winter that it broke with my attempts to release it, just when all the stores had brought in their spring/summer gear so I ended up paying an extortionate amount to get the zipper replaced just to get to the end of the polar vortex we experienced.
Having said that, it hasn't put me off buying another zara coat with a zipper for her this year. They're just too darn cute to resist!
