The shirts on these are awesome! They fit my 2yr old perfectly and the hooded mask is super cute. Avengers, assemble! The pants are a little strange, though. They are really kind of slippery, I guess is the best way to describe them. They tend to work themselves off of my son. They fit him correctly in length and waist, so I know it's not a sizing issue. I think its because he likes to crawl around on the floor a lot and they just work themselves off. Not a big problem- pants aren't a huge concern in our house for him to wear anyway. The shirt still looks really cute with a pair of jeans or khakis or even camo pants. My son may not know exactly who Captain America is yet, but he's well on his way with this cute shirt. I also bought the Iron Man one, and that one is even cuter, the mask is super cool. Definitely suggest getting them! Just don't be surprised if your toddler works the pants off and their butts are hanging out! If buying for a larger size child, probably would fit just fine, but I don't know for certain, as only have experience with the 2T sizes.
