The "all-in-one" is made with a tightly woven, taut twill fabric on the inside, and has a straight silhouette from the waist to the hem, giving it the feel of an engineer's overalls. "This all-in-one is a convenient item that can be used in a wide range of outfits. The front zipper opens all the way down, so you can find the opening that suits you best to match your innerwear... I chose a dark navy color that is easy to wear. It's an extremely simple item, but I asked for the collar to be made larger as a highlight. I'm also looking forward to wearing it as a bottom piece this spring, with the sleeves tied tightly around the waist." from mii
