vivicoco Kid's Pajamas for Boys Girls 100% Cotton Christmas Pjs Sleepwear 2-7

I purchased these pjs for my 4 year old son. I wasn’t sure how they ran so I ordered a size 7. He’s 43” and 42lbs for size reference. The size 7 top is long on him but comfortable. The pants fit well in the waist and are slightly baggy. I definitely think these run small as he’s typically in a size 5! So order one or two sizes up if you want them to last.The material is thin - this isn’t designer quality but that’s fine because they’re more novelty pjs and for the price it’s what I’d expect. They’re soft and not scratchy so that’s what’s most important.The tag says hand wash only and not to put in the dryer. I haven’t washed them yet so not sure how they’ll hold up.
