For tying together any look, I love to quickly stitch up a wide, obi-wrap belt. It's super-quick to sew, and since it takes so little fabric, it's a great way to use those pricey drop-dead-gorgeous fabrics you've been drooling over. This belt makes a smart choice for defining the waistline and lends drama to every look from a cocktail dress to a simple T-shirt and jeans.
The 'sageo' is the cord used to secure the saya (scabbard) of the katana to the obi (belt) of the samurai. Whenever the sword was utilized for display, presentation, or otherwise removed and placed on a stand, it was a matter of etiquette to tie the sageo in a manner that prevented it from loosely hanging from the saya onto the floor or otherwise. As is common with Japan, this seemingly simple act developed into its own art form.
