“Ordered this for our Niece she was going to watch Wizard of Oz. This dress is lovely and fitted her fine. We did get 7-8 and she is 5 as I have always found fancy dress to be smaller than normal sizes.However there is loads of room in it so should last her a while and if she was a small 5 the 5-6 would have been okay but she is quite tall.She loves this dress and the price was brilliant. Delivery was free and came in two days so would definitely recommend this company K Ward”
