My daughter had seen a picture of this costume in a catalog and kept asking for it.  After several weeks when she still hadn't forgotten about it, I finally gave in.  She's 4 1/2 yrs old and the 4-6x fit great.  It was a tad long, so we had to watch to make sure she didn't trip.  Not only was she so excited to wear it, we actually got lots of compliments on it!  It's got great sparkle/colors and fun details (e.g. layered skirt and jagged sleeves).  I found it on amazon and got it for free shipping vs. paying tons of shipping from the catalog where she originally spotted it.  I would definitely recommend it.
