Warm and fuzzy one piece pajamas

These fleece onesie pajamas are all your kiddo needs to be warm and cuddly at home this Christmas season. The buffalo plaid is a hit and the hood is a teenage staple! My kiddo typically wears a size 14 and we purchased this item in a size xxl as we wanted to be sure they could add this over a pajama outfit if they would like to. We also wanted to be sure when they sat down that it wouldn't be too tight on the legs or bottom. So we purposely oversized and they are happy!

So fun and festive for kids

I bought this one piece pajama set for my 6 year old son who weighs 55lbs and is wearing a size small. He wore this to school during spirit week for pajama day and loved it. What's nice is that he could still wear a tshirt underneath it without being too hot because the material is nice and lightweight. This is great for matching family photos and just lounging around the house. It's soft and warm, but not too hot!

Red and black Plaid onesie

My daughter is normally a large or an extra large in clothing. She wanted to buy matching pajamas for her older cousin so we bought one size bigger for her to try on. They will definitely fit my niece perfectly and she is 12 years old. This one piece pajama set is the perfect weight because it's not too heavy or thick. My daughter said it was super soft and she likes that the feet are open so that she can just wear regular socks. This is a super cute onesie for the holiday season.
