I love that this sunsuit has both long sleeves and long pant legs. I also love that it comes in bigger sizes (I’ve yet to find another brand that has this style and goes up to a 5t). Our almost 2 year old is very big for his age and the 3T/4T fits him well, with a little room to grow. He’s currently wearing 3T and 4T clothes so This definitely fits true to size. The only thing I would change is that the sleeves and pant legs taper slightly towards the wrists and ankles which can make it a little tougher to put on/take off especially on wet or damp skin. His old sunsuit (from another brand) is a little bit looser fitting in the arms and legs and I like that fit just a little more, but he’s out growing it so I’m grateful we found this one!
