Worn for the 100-day celebration (Okuuizome) and the first seasonal festival. There are no noticeable stains, but please forgive any oversights. I think the wrinkles will come out nicely if you iron them. There are two sets, so it's also recommended for twins. How about for the Hatsumiyamairi (first shrine visit) or New Year's? Sizes are 70 and 80!! *Please note that we cannot accept returns, refunds, or complaints after purchase.
