This is a set of 7 baby undershirts. The size is 50-60. Includes long undershirts and combination undershirts. Some have snap buttons, and some have ties. The ones on the left in the photos were worn frequently, so they show more wear compared to the ones on the right. The three on the right in the photos were only washed but never worn. The plain one in the front on the right in the photos is a Familiar undershirt (it was already the wrong size when I received it, so it was only washed). The others were purchased from Nishimatsuya, UNIQLO, etc. They can be worn year-round, but the pink flower and yellow lemon undershirts are more suitable for summer (these two are from UNIQLO). Please understand that these are used items.
