Cute shirt with soft material, good quality for price. However, they run small. For reference, my daughter is typically in 18m- I bought size 2T in these shirts and they are still short on her. They raise up on her belly if worn with regular pants. For this reason, I use them mostly under overalls, vests, dresses, etc

Great addition to wardrobe but size up is likely needed.

Size: Large, Color: Navy/French Stripe

Why did you pick this product vs others?: These are super cute, but you may want to size up at least 1 size as they are more of a fitted style and fabric.

Runs very short in torso area

Size: 2T, Color: Mauve/Butterflies

I bought 2T and the shirt came down to daughters belly button. She’s 21 months and I compared it to all my other 2T shirts and these were way shorter so it’s not that my daughter is just big for her age. These run extremely short in the torso.
