Such cute shorts, they look great with any outfit and the quality is awesome! Definitely recommend.
My son is 4yrs old, slender and tall 34 lbs and I got the 4/5 for him. Plenty of room to grow. Can't say enough good things about these shorts. The waistband is extremely comfortable.
Good quality! I ordered the 5-6 for my 5 year old and they are very big! I assume they will fit without sagging next summer. Otherwise great!
