This is a slightly fluffy, thin quilt-like material, similar to cotton jersey. I used it indoors on chilly days. It was very useful, so there is some pilling. ⚠️ Only the blue one is labeled 60-70, and the other two don't have tags, so the details are unknown. The beige one feels a bit larger. I think the beige one is around a size 70-80. Please check the photos on slides 8 and 9. My memory is vague, but I think the beige and the striped one are from Belle Maison. The blue one is from petitjam. Quilted Rompers Frog Rompers Belle Maison
