We live near the beach, so I love finding ocean themed clothing for my little grandson. He loves this colorful swimming sharks crew neck t-shirt. He says it looks "cool." The cotton blend material is soft and and gentle against his skin. It's breathable and slightly stretchy. . The stitching is straight and consistent with no loose threads. We have fun talking about the different sharks, and the shirt looks great with his everyday jeans, joggers, or shorts. If you want some growing room, I suggest ordering a size up. The 5T is just a little long and roomy in the shoulders for my grandson who usually wears size 4. For laundering, I turn the shirt inside out and wash on cold to preserve the print. I haven't noticed any shrinkage or fading. I've been drying it on a warm setting (though cool is ideal), but I’m pretty careful not to leave it in the dryer too long to avoid wrinkles. He's been wearing it since his birthday in February, and so far, it's kept its shape, and seems to resist stains. If you have a little one that loves sharks, this check out this comfy ocean themed crew neck.
