Suit is very cute but sized way too small. Middrift top rides up even though I purchased 2 sizes bigger than needed

Very cute and lovely bathing suit but the bottom is very tight around the waist. The girl is almost 4 years and we bought the size 4.

I ended up ordering a 4T for my 22month old daughter. Even that is a little on the snug side and she is not really a chunker anymore. I think these run a little small. The bathing suit is very well made, so there isn't alot of give to the fabric, even though the size chart said she should fit a 2T, we ended up wtih a 4T. This bathing suit is awesome though!
