This costume really is as great as the reviews suggest.  I purchased a size 2/3 for my 2-year-old's 1st trick-or-treat outing 2 years ago, and it was a hit with him, we his parents, and our friends and neighbors.  He was kind of swimming in it that year, I have to say, but we made it work.  I was amazed at how realistic it looked, how durable it appeared, and how heavy-duty the clasps on the jacket are.  In the 2 years since, it has gotten occasional dress-up play, and it continues to look brand new.  And now this month my son who is now 4 years old wants to wear it for Halloween yet again!  Yay, I say, as I won't have to try to find another great/expensive costume, so this thing is paying for itself...  Plus the 2/3 fits him very well now (at age 4), so it appears to run a bit big.  If I could think of any negatives, the aforementioned heavy-duty metal jacket clasps seem too difficult for a child to easily open and close, and so I find that I need to help my son get in and out of this costume whenever he wants to dress up in it.
