My daughter is 6 years old but small for her age.  The size 3-5 fits her perfectly. The tights are good quality.  They're a good thickness.  They're soft.  The waistband is perfect.  It has a nice gentle stretch with a soft band that's wider than other little kid tights I've seen.  It doesn't dig in or twist.  My daughter loves them and wears them often.  They've held up to washing quite well.  I got these on sale.  I'll probably order more when they go on sale again.
