In the stores, I have only been able to find size "6" in this product, so I was very pleased to find them in size "4" online. They are well made, bright and colorful; they could be improved by including more of the characters, or having more than one set so you were certain to get your granddaughter's (daughter's, etc) favorite character, but all her other "character" underwear sit unused now that she has "My Little Pony." The price was also less than in the stores.
