This costume was great!  Make sure that you buy one size up because I was going back and forth with the med and large and I got the large (listed as 12 months) for my 6 month old and it fit perfect with just enough room for heavy clothes underneath (it's cold in Oct. in Chicago).  Washed the costume before putting it on my son and it held up and was soft and warm.  Made our 1st Halloween even better to see our son in such an adorable costume!  =)
