My daughter was invited to a disney princess theme party. She wanted to be Ariel ! So the search started. From Party city to Target,Costume castle and .... I also checked Disney online .no doubt  the only good quality  I found was from disney store. It also was the priciest ! then  I found this one with really bad reviews for  quality of the dress. one review was about how ugly is the back of this dress. I risked it and ordered the dress. yesterday I got the box ,I opened it with a true fear....and it was adorable. I mean it is not a quality dress but if you ever checked the ones in Target this one is not worse than them,even a little bit better honestly. other Ariel dresses are kind of hard to handle  by a little girl because they are long and tight to show the mermaid tail. this one is just perfect. she can walk and dance in it! the TuTu skirt is just a dream for any little girl.the back is ok for me.they always use lower quality plastic texture on back of cheap costumes,and this one is no exception also. but it certainly match with the rest of the dress .it doesn't look like left over as the other review said. I agree with the ones that said the sewing is poor! some parts of mine(around the neck) are kind of loose that i decide too fix them today. my little one is 3  but I ordered the size 4-6 x she is really slim but i'm very happy with this bigger size. overall if you can afford Disney buy that,( this one is even cutter ,I'm talking about quality ) .If you are not buying from disney,then this is the one, and wayyy better than other cheap ones.
