All in Stitches

There is different quality of clothing. For some, the quality comes in the details: pockets, colored stitching, appliques, ect. For others it's the material: silk, cashmere, wool, ect. While, others consider quality according to it's durability under outside factors, such as, exposure to sun, dirt, wind, repetitive actions (crawling for instance). All in all,  a quality piece of clothing to me is not only it's ability to hold up to my children's crawling and climbing over rough objects but also it's functionality. I'd rather not spend all my day buttoning and unbuttoning clothing to change a diaper! What qualities in children's clothing do you value most?
