I have been buying these style dresses all summer for my 2 year old daughter. I didn't want to buy this one because the price is insane for a child's dress however a family member got the dress for my daughter. She's not even 3 year we have a 3/4 it's very tight and long. I have gotten 50s style dresses for her all summer that fit amazing for under $10 and they will all still fit next year just as last year's fit this year. It's very upsetting this dress is so tight I don't think it's making it the rest of the summer and it's one of the few dresses my daughter asked for specifically. I'd say get a size up but the length of this dress makes me think if I got the size bigger she would be walking on it. Not worth $3 let alone $30+
