Kids' Vibrant Flamingo Long Sleeve Two-Piece Rashguard Swimsuit

I'm really disappointed in this purchase. The sizing between the two pieces is all wrong. The top arms are too short yet the body of the rash guard is too wide. The bottoms are so big they wouldn't even fit my five-year-old. So now I have a swimsuit where the top fits too small and the bottoms fit too big. I figured that the quality would be really good based on other reviews, but the material is very thick, stiff, and not very soft. I ordered this suit based on the fact that the girl in the picture was the same build as mine. Mistake.
