This is the most durable, well-made Halloween costume I've ever seen. It's also very authentic looking and cute! My son won a neighborhood "best costume" contest with this one this year. I also loved the fact that it's very well suited for the cold Halloweens we have in Minnesota. It's easy to put warm clothes underneath and not compromise the costume's look.

The pants are adjustable (it has suspenders), however as other reviewers noted it does run quite large. My son is a couple months' shy of 4 years old, and he's small for his age. I wasn't sure which size to buy -- I chose the 4-6 size so that he could wear it for a number of years. I kind of wish they had more sizing options cause neither one seemed like the right call for my 3-year old. It turned out OK, though. It was clearly a little bit big on him, but not to the point that he was swimming in it.

The reflective stripes were great in the dark for safety purposes. And the sleeves go down around the thumb (so it's kind of like partial mittens). It helps keep the coat in place. My son thought that was really cool.
