Lovely summer dress, arrived well before expected date.Its a very light material, perfect for summer.My daughter is 5 (she 2as 5 only 2 months ago) shes a little taller then average but is of a normal build, we got the 5-6, and it fits perfectly, I'd say if your daughter is closer to 6 then 5 I'd suggest buying the size up.For the price its great summer dress.Lovely dress :-). My daughter is in UK size 5-6 so I bought this in that size and as you can see it fits perfect. She loves it too. Only reason for 4 star is because if you want to have the straps like any normal top they slip of the shoulders, they are slightly to wide apart if that makes sense. But perfect for halter neck like in the picWell my grandchildren was chuffed to bits.Lovely beautiful dresses. Though little bit big but they still fitted to be honest I rather that means thry get the use out the dresses thry look lush. And plenty of growing room . They was over moon. And worth buy. My daughter going order more.I bought diffrent sizesPurchased age size 7-8 for my 6 year old g'daughter and it fits just fine, with some growing room. Tie shoulder straps can be tucked out of sight if they prefer to go strapless. Am hoping she may be able to wear it as a skirt when she gets taller as elastic top should allow for this. Lovely vibrant colours and nice light soft cotton-feel material, perfect for summer and holidays. She also loved the necklace that came with it. Great value and arrived from Amazon within 5 days. Very pleased with this purchase.Lovely design and vibrant colour. Good sizing too. But, the finished quality is poor. The hem and shoulder strap stitching both came away within a couple of uses. Make sure you have a needle and thread handy.
