I ORDERED 2 BIG SETS, MY DAUGHTERS WEAR 12/14 BUT THE BIG SIZE WAS BETTER IN SIZE 7/8 THE LENGTH WAS GOOD BUT ONLY SUITABLE FOR THEIR SO BIG 7/8 ME IMAGINE THAT WILL GET EXTRA BIG AS 10/12 CAN BE. PANTS DO NOT STRETCH AT THE WAIST. IT HAS A FLEECE INSIDE AND LOOKS WARM. I ONLY OPENED ONE PACKAGE AND WAS BACK IMMEDIATELY. I WILL NOT ORDER ANY MORE BECAUSE I NEED XXL AND YOU DON'T HAVE XXL. IF YOU WANT TO BUY THEN REMEMBER THE SIZE IS SMALL. THE AVERAGE IS LIKE 5/6 IF YOUR BABY IS SKINNY MY GIRLS ARE NOT FAT BUT LARGE AND LARGER THIS IS MEDIUM SO DEFINITELY IF YOUR BABY IS 10/12 OR 14 ABOVE YOU NEED SIZE XL.
