Although it's size 95, it's a loose fit, so size 100 might also be good! Please check the measurements♡ It's winter-spec, with a cotton lining on the inside. Since it doesn't directly touch the denim, it should be gentle on your child's skin(*´˘` )♡ For those in snowy areas, it might be difficult to dry if it gets wet, but how about it as a fashionable winter outfit? I bought it and kept it in the closet, so it's unused. I wash and clean items I buy before wearing them, so I've already pre-washed it once. Please understand that this is a used item m(__)m It's made of slightly thick and sturdy material, so I will compress it slightly when shipping.
