These are Uniqlo newborn short-sleeved undershirts and combination undershirts. I bought them in March of this year, pre-washed them, and gave birth in April, but it quickly became hot, and they only got worn a few times each before my baby outgrew them. They are white and yellow, so they can be worn by either a boy or a girl. They are still in good condition, so I hope to pass them on to someone! I will fold them compactly for shipping from home storage, so please forgive any folding wrinkles. Thank you for looking.
