It fits like it is suppose to. It’sSo adorable that I actually bought another one. My granddaughter just loves wearing thisOutfit.Bought this for my 7 year old. She usually wears size 7. Ordered a 7-8 and it fits perfectly. Lightweight material is perfect for summer.Loved the outfit it definitely was ture to size, however I did have to take in the straps because they were a little large but nothing to outrageous.my daughters torso is a bit short so the top was a little long so we folded it in… but overall we are loving it!I got this for my daughter a few years ago and about to purchase another one. It was so beautiful.I got the butterflies in size 5/6, which is a size 120. It was a bit small for my small 6-year-old who is about 43" tall and weighs about 40lbs. I'll be getting the next size up. It wasn't tight around the bust, but the crotch didn't give much room for movement and the skirt/legs were a little shorter than she and I preferred, though the length was about like in the picture, hitting a bit below the knee.The culottes/jumper style means my kid can be upside down anytime. The top slides on and off easily, so kiddo can go to the bathroom without help, unlike some other jumpers that have a zipper.Some people might think the bust has too little coverage, but I think it is perfect for playing in the summer. To wear it "out" as a dressy outfit you'll want a shoulder wrap of some sort.The fabric is nice and light, exactly what we needed for long pants in summer, and feels a lot like a smooth viscose mix. I think that's what the 60%人棉 means -- 人棉 translates literally to "people cotton" which I think translates to viscose. The rest is 35%锦纶 (nylon) and 5%氨纶 (spandex).Please excuse the fact that my measuring tape only has inches. I placed it so you can see the length measurement as well as the shoulder/crotch and inseam measurements on the size 120 (5/6).Don't hesitate in buying this outfit. My granddaughter loves this outfit. True to size.Brought this for my grand she's 5 but I ordered a 6/7 just because and it fits perfect, looks cute on her.it might be better to go up a size if you want it worn more than once. I got the exact size my granddaughter wears and this came up a bit short on size. It is allot thinner than i thought so wont be able to get too long of use out of it.I am so happy with this jumpsuit! My granddaughter loves it!This is not a rompers. It is a long dress. Fits my daughter perfectly and it's beautiful but not what I ordered.
