This is a set of four baby undershirts for summer. My baby was born in mid-August, so the period of use was short, and I think they can still be worn. The beige lion-patterned and the dull blue ones are 100% cotton mesh. Only the cream-colored car-patterned one was worn for a slightly longer period, so it has been worn more often, and the tag is faded. I hope to pass these on to someone who is running short on summer clothes or who missed out on buying them, as the hot days continue. These items have been inspected by an amateur and stored at home. Please refrain from purchasing if you are sensitive to such things. I will try my best to accommodate changes to the shipping method or price reductions. Please feel free to comment if you would like to purchase with other items or have any questions (*^^*)
