Love this line of products. The fabric is great quality, the colors are vibrant.They do run about a size small—I would recommend sizing up.Docked a star for the design of one pair of pants in the science/rainbow/dinosaur themed set. My daughter loves dinosaurs and always wants to wear the Dino shorts from the (matching) shorts set I got. So I ordered the pants for Fall weather and she was thrilled to see her favorite dinosaur fabric. But the blue pair that says ScIENCe using elements? Has element 99, “Electrone,” for the E. That doesn’t exist. I think that einsteinium would fit— that’s the actual element 99, and does conveniently start with an E! Truly bizarre. If you’re buying these since you’re actually a science nerd, just be aware that the blue pants will probably make you a little grumpy every time you see it.
