Who else has tall skinny kids?

This is my 10 year old in an 8 slim from justice. She really needed a 6 slim in the waist but the 6 and 7s showed booty cheeks so that was a no! The 10 slim she could fit both arms down the sides with room and they fell right to the ground. So we decided to get the 8s because they at least stay up even though she can fit her arm in there and the length was ok. 🤷🏻‍♀️ and the shorts with the adjusters looked like a parachute and were so big on her legs certain movements and you could see her underwear. No winning! 🤦🏻‍♀️
