My son is 3 years old and small. It weighs 27 pounds and is 36 inches. Usually the 2T fits him perfectly and the 3T gives him room to grow. I bought these thermos in size 3T and the top fits him perfectly and so do the pants but they are a bit longer. I like that it's soft, the color is the same as the picture and good quality overall. Not only do they work well as undershirts, my son also likes to wear them as "Japans" (pyjamas). I will buy more in 4T. If it was cheaper than $23.95 I would buy a lot more flowers.
