it may run small for some kids

my boy always wears a couple months down for bottom (still wears 18mo but he's 26mo-old), so i expected these to be quite baggy. Turns out that they are not - they fit well, not too tight, not too big. I like how it fit my kid, but kids who wear their age may want to go for larger size.

I bought this for my 6 yr old son. Based on their size chart, small would be the right fit. However, the shirt and pants are too short. We planned to use this for a school fashion show in May and hope to also use it for Halloween, but it does not look like it would fit him by Halloween time. Also, a picture of the packaged product would have been helpful because the packaging says it's for age 4 to 6 yrs; this info is not included in the sizing chart. Had i known this, i would have gotten medium. I returned the size small and bought a medium instead. The costume itself is nice and looks well made. I just wish I didn't have to go through the hassle of exchanging it for the right size.

Well, my kids have fun on it sometimes but it's a little too small, even for my 20lb baby to fit his tiny butt on it.  They mostly use it as a stool to get cookies from high places...

My 11, 10 and 8 year old kids who are small and thin are a bit big for these.  The width is fine but they seem short and look a little funny when on because of this.  However, the price is good and if you won't be wearing them a lot they're probably "good enough" if your kids aren't picky.

I got this for my son and the arms were a little short. It seems like a tad bit small for a 2T. It could be my boy just grew out if it quick, but he only wore it like 2 times.

It says it fits 1-4 yrs old.  My son is 2.5 and it is on the widest setting and just fits.  There isn't much room for him to grow and I doubt he will be able to use this at 4. Granted my son is not small, but he is not off the charts either.  We ended up keeping it because we needed a helmet for his bike and it is light and he will wear it.  Just be cautioned if your kid is older or larger, this may not fit for long.

Had seen this and knew that it ran a little bit small so it was perfect for the child it was ordered for.

This is not small. It's like a junior small rather than adult small. For adults it's probably like extra extra small.

My ten year old loved it. We found that it runs small. The head gear is also tight on the head.

it fits a little small.  I have a child who was in the 40% for weight and it was still tight.

I say it fits somewhat small because compared to GAP 2T/3T, it is smaller compared to those. My kid is on the smaller side for 22 months old and about 25lbs and it fits great on him. So it's leans towards to the 2T side. If your kid loves Thomas and Friends, GET IT NOW! they want to wear it all the time.

If you get one go at least two sizes up.  Got 2 (3 and 6 year old girls),  both were much smaller than other clothes labeled the same size.

It was nice but my daughter will have to enjoy it. It was sized very small.

I bought it for my four year old. It was a little small and I wish the material had been more life like. It seemed a little thin. As for the size it does run small. My son just turned four and it was a very tight fit. We had the suspenders on the longest notch and the knickers were "up'' a little far. So we won't be taking any pictures from behind... but other than that very cute!

It's OK for what it is, but it's pretty small, barely fits my 6 year old.

My nine-year-old could fit it size way too small size is not accurate
