This is a set of one long-sleeved two-way all and two short undergarments. All items are 50-60cm and 100% cotton. The short undergarments are easy to use as they fasten with buttons on the outside. I gave birth in April, but these clothes weren't used much because it quickly got hot and my baby outgrew them. They show some signs of use, but are still usable, so I'm putting them up for sale. Instant purchase is welcome. Thank you.
