You are getting a very popular Hanna Andersson piece, released in 2009 Holiday season.
Size is 90/3/3T, and the dress is really in like new condition, with a little wrinkling from storage, but those should come out once it's in the open air for a while.
I do ship within 24 hrs of payment!
I have other HA taffeta holiday dresses listed in blue and black/size 120. Possible sister dresses!
