We bought a 9-back "Boxer Cut" underwear in size 7-8 years. The bag says size 150 and they fit our 7 year old great! He's about 68 pounds. and 4'5" tall, usually wears an 8/10 fitted pant. Our favorite thing about them is the cute prints! It's hard to find inexpensive underwear other than toddler sizes with fun prints or patterns. We will definitely have these buy case again.
