Miki House 2-way Rompers 50-70 Two-Way All The ones with many animals have more pilling. Both have areas where the patches are slightly raised. Both have a worn feel, but since they were only worn for a short period during the newborn stage, the fabric is still fluffy and there doesn't seem to be any noticeable stains. The size is 50-70, so they can be worn for a longer period. They are all-season material, so I think they can still be worn until the chilly season of the rainy season.
