These Japanese-made knit pants utilize the seamless Whole Garment knitting method, known as the "second skin," and don't have any seams to restrict movement. They offer an incredibly comfortable, stress-free fit. The shoulder straps have buttons for size adjustment. They're useful for babies from around 70-80cm, from the napping stage to crawling. The light gray soles add a stylish accent to any outfit. They cover the feet completely, so socks aren't needed. The easy-to-match muted pink color is cute. They can be worn alone, or paired with a matching cardigan or knit bonnet for a lovely baby-style look. They also pair perfectly with MARLMARL bibs. Model: 4 months old, 60cm / 1 year 1 month old, 69cm I didn't get a chance to wear these because my child outgrew them. I hope someone will love them!
