Although it's Little Girl's jacket, it runs big, which I'm happy with it. I purchased a Small, when I received it, it really looks like normal 4T or even larger size.The fabric is very very neat, and the inside zipper is interesting. Here is a previous review writen by Lena, whos said just what I want to say: The coat maybe a little on the large size but I order it that way to have her get more wear out of it. She loves the fur around the hood section, will keep more of the cold air off her face. The coat itself is very warm with two layers noted on the inside. Zippers work fine and are out of plastic and not metal so I don't have to worry about rust.Very nice for the price. Just right for west coast winter. Have two zipper enclosure. The interior fleece part just lines the zipper, neck, and sleeve (hand opening) area. The lining inside is just nylon. The hood is detachable.My one major complaint-The sleeves are rather long, and since it has the faux fleece lining on the inside, makes it rather hard to roll up the sleeves.*Edit: After having my little girl put this on when the weather finally turned cold, she figured out something that I missed...There are thumb holes on the side of the sleeves (the faux fleece inner sleeves) and once she slips her thumbs through it the long sleeves become a handy little mock finger-less gloveGreat quality coat and the fit is perfect. It's a medium weight coat but keeps my daughter nice and warm in Michigan weather. My older daughter has a hand-me-down older version of this coat that is down filled. (Which is why I purchase this one) Also great quality and keeps her super toasty! Although this particular one is not down filled it keeps her just as warm. She has been wearing it for about a month with no problems. Has two zippers for extra warmth and she loves the cuffs with a hole for her thumb.Very cute jacket! I'd say it's medium-weight--nice and warm, but perhaps not enough if you live where the winters are very cold. For us, this is perfect for colder days. It does seem to run a bit large though. I bought the 6x (lg) for my 6 ye old and it's long on her; even my 10 yr old can squeeze into it.Not actually a double coat (does NOT have a removable interior jacket, it's just made to look like it does). It's a decent weight everyday coat for Tennessee climate. Will have to layer up if we get snow to play in though. 5 year old loves it and it is really cute on.I as well as my daughter like the coat. While playing in the snow today she was warm enough. Only disappointment is that I thought the vest was a zip in/zip out kind. It is only a fake vest piece in the front.I bought a larger size as you can never be too sure when ordering online. It's nice and long but the sleeves easily pull up and is a somewhat slim fit. Perfect for Australian winters as it gets cold and rainy and windy, but not freezing. My daughter will get a couple of years out of it. Gorgeous coatMy daughter loves this jacket. Very warm. I especially love the soft purple inner lining. The jacket looks just like the pic. I also love the fact that there is a place to write her name and other information. I recommend this for others to buy.
