The LaLaMa Boys Airplane short set fit perfect. I ordered a 2-3 year medium and he is 2 years old and this fit great. It isn't to tight or to loose. This should fit him next summer unless he has a large growth spurt. The top has a large plane on the front with a crew neck and short sleeves. The bottom is a pair of shorts with smaller red and white planes all over them. It is such a cute set.
The set is made of cotton blend and is comfortable to wear. It is machine washable. I turn them inside out and washed them on the normal cycle. I wasn't sure if they would shrink in the dryer so I line dry them. I was really pleased with the quality and the design.
