I wanted a dress for my nearly 6yr old, who is a little small for her age. I nearly got her a size 6-7, but was worried it would be huge for her, so in the end got a 5-6 - it was huge on her. The dress itself is lovely and so pretty that I gave it to my niece instead of returning it. The Cinda label said 5-6yrs, but the actual dress label said 10, so I wondered if it had been mistakenly labelled, as all the other reviews I've read for these Qi Pao dresses say the fit is just right. Luckily, on the Cinda website the measurements are given for each dress size, and these seem to be accurate as I nervously ordered a 2-3yrs dress based on those measurements and it fits perfectly (this dress label says 6, so I think the Cinda labelling might be a little off). All in all, I'm very happy with the dresses - the first one was red, the second baby pink, both gorgeous - they are really good value for money, and the sweet little purses that come with them are the icing on the cake, but would recommend that you visit the Cinda website and check sizing before ordering.
