This is a classic down coat from crewcuts, the children's line of J.Crew, perfect for the cold season. The color is navy. I purchased this coat secondhand, and it was only worn a few times for outings, so I've only worn it about 4-5 times. Upon close inspection, there is a faint stain on the chest area, but I personally don't mind it. Other than that, I didn't notice any other issues, but please understand that there may be oversights due to my amateur inspection. The sleeves have ribbed cuffs to keep the wind out, and the inside of the coat is fleece, making it very warm! You can remove the attached belt if you don't need it. Small down feathers are attached to the fleece lining. Size 10 is for 10-year-olds according to J.Crew. It's probably around 130-140 in Japanese size. This is a used children's item, stored by a private individual. Please refrain from purchasing if you are sensitive to such items. Please comment before purchasing.
