This is a knit set from the British brand, EMILE ET ROSE. The size is 18m, which I believe is around 90cm in Japanese size. My son, who is of average to slightly small build, was able to wear it from around 1.5 to 2.5 years old. The top has buttons on the back that can be fully opened, and the pants have an elastic waistband, making them very easy to put on. It comes with a hat, and when worn together, it looks adorable, like a little gnome, and I received many compliments. Please refer to the second photo for a picture of my son wearing it. The color in the photos of my son wearing it appears lighter, but the actual color is closer to that in the fifth photo. I only wore it a few times for outings before my son outgrew it. There might be a slight discoloration on the white collar, but it's barely noticeable in the photos, and there's no pilling, so I think it's in relatively good condition. I recommend this to those who like overseas children's clothing and baby clothes brands such as Rachel Riley, Amaia Kids, and Maman et Moi.
