Old UNIQLO Navy tag Size is indicated as 57. I think it's XS to S size. Please check the measurements in the photos. Please understand that there may be some errors due to amateur measurements. I purchased this item several decades ago, but the condition is very clean and I think you can still use it. I have hardly worn it, and it has been stored at home for a long time. I would be happy if someone who likes red, or someone whose lucky color is red, would use it ♡^_^ I try my best not to miss anything, but please understand that this item has been stored at home. ★ It will be shipped folded. Please note that there may be creases.
