I haven’t washed it yet so I can’t speak to shrinkage, though I expect it will shrink a little (like most cotton items, but I don’t remember if this is 100% cotton or not). I always use cold water & low heat so I see minimal shrinkage on all my kids clothes. The top has no stretch at all, so I’m assuming it’s 100% cotton. But it does have a nice loose fit without being overly baggy. I think it’s a little longer than expected, which I really appreciate bc I hate when the “tramp stamp” area is exposed on my kids.My daughter wears anything from a 2T - 4T, depending on brand & what it is. She’s a little shorter than average, but weighs more than average (around 31lbs). As someone else said, “my kid is not a string bean, she’s a tater tot.” I think I ordered a 2T-3T & that size is honestly so much better than just a regular 2T or 3T on their own.I often get boys clothes for my 2 y/o girl bc she has very sensitive skin & eczema that’s irritated by polyester, ribbons, ruffles, glitter, designs, embroidery, etc. It’s hard to find more “plain” girls clothes, in cotton, that isn’t super expensive, but the price for this top was good.I think the listing might have said sweater, but it’s not thick like a sweater. It’s also not exactly like a thin t-shirt material either. The inside is more like smooth terry. I’m glad that it’s not a “real” sweater bc my daughter sleeps hot & getting sweaty leads to more rashes.This type of clothing is exactly what she needs to be comfortable. It’s not too heavy, doesn’t have a ton of embellishments & the design doesn’t go through the inside & irritate her. It also has a great fit. The pattern is super cute without being too boyish — or girlish. I love clothes that can be unisex without being yellow, green or orange!! And the best thing EVER is finding clothes, like this top, that are comfy enough to wear around the house (& even to bed!) while still being cute enough to wear out (without looking like sweats or pj’s).It also came packaged nicely with a pretty thank you card — but I’d buy again no matter how the item came (unless it was used/dirty or damaged, of course).Was anticipating for it to fit a little loser since my song fits in a 3t I bought a 4t but it definitely fits more like a 3t. Still super cuteMy toddler loves trucks, so it’s a win in that regard, but it’s quite light for a sweatshirt; more like a long sleeved shirt weight.I will start off by saying that it IS listed as green so I shouldn’t have been surprised by the dark Kelly green shirt I received. The example picture was more blue, like the shirt I am comparing it to in the picture I took, so I was let down. The shirt is also not a sweatshirt. The style is as such, but it is as thin as a cotton tee.This is a cute shirt with great colors (green shirt with embroidered beetle) but it’s just a thick long sleeve shirt. This is not a sweatshirt. I️ expected thicker, warmer fabric. The look of the design is accurate to what’s shown online, but don’t think I’d buy more as they are not warm enough for fall/winter in the Northeast.The sweatshirt is picture #3 without the embroidered shark. Overall, sweatshirt is lightweight and washed well. The sharks are super cute as pictured. Ordered 5t for my 2 1/2 year old who is in 4/5t Carters.Bought matching shirts for my kids’ big themed bday party. Son is 2 but bought 3T and it barely fit. My daughter wears 7/8 but is slim so I tried the 6 and it was a photo finish. They are not sweatshirts—definitely a thick shirt. The textured beetle decal is so cute! I recommend this shirt but it does run slim and small. ?Wow! Actually very impressed with this!I bought this on a big gamble since there were no reviews but I really lucked out! This is a great quality sweatshirt. If I didn't know better I'd think it was from Hanna or something! Buying more for sure!!!The bug applique is stitched on and embroidered so it's not going anywhere. The back of the embroidery is very soft so it won't irritate your kid's tummy if they wear this without an undershirt. I've had problems with appliques causing irritation in the past.I would describe this as a lightweight cotton jersey sweatshirt. The inside is french terry, not fleecey. The colors are true to pictures and the size is consistent with Carter's or Hanna. My child is typically a 2t, but I ordered a 3t for oversized look/longevity.There is no tag at the neck to bother your child. My sweatshirt had no loose threads, and it washed up great with minimal shrinkage. Delivery was lightning fast. Overall, a win for cute fall layers!If this review was helpful, please hit that button ?This product is not worth the money - you will be charged postage if you try to return it.
