Runs very small in my experience. Bought "size 6" for my 5 year old who wears a 6 in many different brands. Didnt fit.was way too small and tag reads "5-6" so then I sent back and order next size, "size 7" tag says "6-7" still too small have had to return again for "size 8". Fortunately returning has been very easy and the dress itself is very cute and good material just sizing way off.
