I haven't worn it for one season. I usually wear size 80, but the romper type seems a bit small, and the button on the bottom comes undone. For reference, 76 cm, 9 kg. The button stays closed when standing, but comes undone after sitting for a while. There is no size listed, but it's 80 cm. I bought a separate type, so I'm selling this one. I also have size 70. #MikiHouse #DoubleB #AkachanHonpo #ToysRUs #BabiesRUs #Nishimatsuya #Birthday #Shimamura #Baby #Kids #HankyuDepartmentStore #Harukas #70cm #80cm #Boy #BabyClothes #Rompers #Jinbei #Festival I have a lot of other baby clothes as well. Combined shipping discount available. ⚠️I might use it for the next child, so no price negotiations.⚠️ I will not do business with those who still comment asking for a discount. Baby clothes are worn for one season or less. I haven't worn them much, but they are still used items, so please refrain from purchasing if you are sensitive to this.
