My daughter loves Dora the Explorer. She gets the choice each night on what she wants to wear to bed. So of course she has multiple character options. However, one of her favorites (and one that gets washed A LOT) is definitely her Dora the Explorer Sleepwear set. She wears them so much we actually got her multiple sleepwear sets. (Of course, they feature different Dora designs. But they are the same set - 100% cotton, etc.)
It features a long sleeve shirt and pants, so it is great for autumn and winter time frames. This sleepwear set is also easy to put on. So kids that are learning how to put their pajamas on all by themselves will have no issues. Not to mention, they are comfortable.
I love that it is 100% cotton. However, my biggest downfall for the Dora the Explorer Sleepwear set is that it is NOT flame resistant. Plus since it is 100% cotton, there is also the risk of it shrinking if you do not wash the item correctly.
Another positive is that I haven't had any issues with the colors fading. Not to mention, there weren't any color bleeds into other colors during washing either. Overall, I had great success with the Dora the Explorer Sleepwear set, and I will definitely get more sets like this in the future.
