My kiddo asked to dress up in Elsa's "spring fever" dress for our WDW trip. The normal costumes seemed so cheaply made I didn't think they would survive the trip so I took a chance on this dress. SHE ABSOLUTELY LOVES IT!  It's close enough in style but so well made and comfortable. Also the "official" costumes were so long I think they would be hazardous but this lovely little gown is tea length which was so helpful.  My kiddo wears a 4T or 5 in normal clothes. I ordered a 5 and a 6 to determine which fit better.  Both fit but the size 6 had a little more wiggle room (so she can wear it longer) without being too long etc. The sheer lace makes this gown look so adorable too. If your kiddo likes to dress up or wants a Frozen Fever inspired dress, I don't think you will be disappointed!
