I have a tall 3yr old who normally wears a 4t. I was going to size up but reviews said the dress ran a little big so I got the 3-4t and she still has room to wear the dress for a while. All in all I’m pretty satisfied. I ordered the dress at the last minute and it came right on time. My daughter also loves the dress, especially twirling in it ?The orange color was much brighter then I anticipated.My daughter loves dresses but always complains about not having pockets to put all of her stuff. You know, rocks, crayons, toys, pencils, sticks, bugs, candy, her hands, etc. She is an active 5 (almost 6)-year-old and loves wearing dresses with funny tights. I got her this dress because of the pockets and it is now her favorite dress! I am about to purchase her more in other colors.Sizing is spot in. My daughter is big for her age. She is 54" tall and weighs 65 pounds but she is not round, just stocky. She wears a size 7/8 right now in tops (this includes shirts from Cat & Jack at Target and Wonder Nation at Walmart). I wanted to get her this dress a little big so that she could hopefully wear it next school year as well. So, I bought the 10-12. It is a little big on her, as expected. The skirt portion has a nice length to it so that it hits her about the top of her calves, a little longer than the bottoms of her knees. It twirls very nicely when she spins. The sleeves are not cap sleeves and actually cover her shoulders. Then the pockets!!! They are real pockets and not those little shallow things that other dresses will have. These pockets are deep enough for her to put all of her things in and still put her hands in too.As for the color. I ordered the red. The red we got is a bit more towards the orangey side of red than the picture shows. It is still definitely red, it's just not as scarlet red as the picture.Like the fabric and fit. Used for Father Daughter Dancemy daughter like it. The stuff is softI like the cut of this dress. The material is nice and opaque, but also a bit rough to the touch. The problem I had is that their "white" is not white, it has this kind of purplish cast that bothers me. I asked the company if this was normal, and they said that was as white as they could get the material. I asked if I could bleach it to a pure white, and they didn't recommend it, so I just sent it back.Comfortable and cute.I bought this for a girl who isn’t really frilly but she is still “girly”. She’s 9 (and a half). She couldn’t stop twirling! I bought the 10/12. It fits and will fit her into next year. She kept saying “a girl can’t ever have enough pockets and twirling”. I can’t believe a dress so simply designed would be such a hit!The fit is only in the bust and sleeves. The sleeves were a good length. She had room to grow (and she’s a good size 10). The bust fit well with growing room. The length was a couple of inches above her knees. With leggings she could feasibly wear this 2-3 years. The fabric is thicker than T-shirt material and flowy. If it was offered in a print she liked I would buy more.
