Like everyone else says, it runs very small and is cheaply made. I did order the next size up,small(4-6) for my soon to be 4yr old who wears size 4. The dress just fits her but the tights don't fit.  They are baggy around the feet but too small in length.  They barely go up to her waist so the crotch hangs low.  This company really needs to fix it's sizes in everything.  And cheaply made is putting it nicely.  I can see the seams almost starting to split and if it pulls just a little I can see it splitting open.  I only bought it because my daughter wants it for her party.  I paid $34 and it's definitely not worth it but I can't find any other strawberry shortcake costume that looks like the real character on TV. I will have to shop around for new tights that fit. Oh, and the emblem on the top looks glued on or ironed on and it's crooked.  I will call the company to see if they can send me a new one.  Maybe the tights in that one will be bigger, who knows.
