I purchased a kids costume on October 9, 2016 from the store on New Circle Road in Lexington....I told my grandsons parents to try it on him as we didn't have time to try it on...they didn't and on Halloween the size 10 racing car costume was too small and he couldn't wear it..had to find another one elsewhere..can I get a size 12 in this costume since he didn't wear it at all...I paid $42 for this one and didn't realize how small they ran...we held it up to him at the store and it looked true to size but was very very short in the crotch and he was afraid it would tear..please advise me...this is a lot of money for a costume and at least a size 12 would allow him to wear it next year...thanks
