My daughter wears 5T clothes or XS in girls sizes. I ordered the 5T and it was too small. I had to reorder in size 6, fit perfectFits my 7 year old puppy lover perfectly! She absolutely loves it!Got the dog print for my dog obsessed 5 year old, she’s in love! She’s in a girls small for clothes so i got the 6/7 size here and it fits pretty well. A little room to grow, but no gaps any where. Haven’t washed it yet, so i can’t speak as to how it’ll wear with time. But all in all, very satisfied.Fun little bathing suit for my 6 year old who loves dog. Fit was well and as expected during ordering. Shipping time was fast. Colors and print appears to be nice. Not faded. Held up nicely at the water park and during wash. Washed in delicate and hang dried.The suit is a little big for my 7 y.o. The material is good however, the way the suit was sewed is not so great. Lots of loose thread ends that weren't cut off.My granddaughter felt a little embarrassed because the legs are cut very high.It is an extremely cute swimsuit, and my 5 year old daughter loves it. However, the mermaid style is cut way too high and way too thin in the bikini area for a 5-yr old. I will not be letting her wear it in a public setting. Additionally, it’s too long in the torso.My granddaughter loved this bathing suit. She wanted to wear it all the time instead of a shirt. Lasted all season too.Muy bonito pero el paquete se perdio
