Great Toddler Shirts
These are awesome shirts! They fit true to size, my 2.5 year old fits comfortably into the 3T. They're soft and high quality, with cool patterns. I would say mid weight material, seems high quality but wouldn't be great for super hot weather. Will definitely buy again.

Great for Everyday

We have a pretty big toddler and these are the perfect every day shirt. Great price, easy to wash and the fit is perfect for our big boy, who's got a long torso and most toddler clothes are not long enough. Coming back to buy more
