I purchased these items at Birthday in September of this year. (The blue-gray coverall is cottoli) I intended to have my child wear them in the fall and winter, so I pre-washed them. However, my baby exceeded 7kg at 2 months old and outgrew them without ever wearing them, so I am putting them up for sale. I washed only these four items using washing detergent from Shabondama Soap. They have wrinkles because they have been pre-washed. Please purchase only if you understand and agree to this. Thank you.
