It's no secret that Japanese culture is infiltrating what we think is trendy. We have sushi restaurants springing up everywhere, and the movie "Memoirs of a Geisha" won multiple Oscar awards.

So it should be no surprise that Japanese design is influencing fashion designers around the world. The runways for spring featured a distinctly Japanese influence — the obi.

The obi is a belt that fits over a woman's kimono at the waist. It has a long tradition dating from the Edo period (1600-1868).

The spring runways in Paris were treated to obi-inspired designs at Lanvin and Dries Van Noten.

These high-waisted belts add curves to any outfit — from elegant professional wear to casual tees. It's an extremely modern look to cinch an outfit with its smooth and satiny texture.

Most designer belts are ridiculously pricey for the average college student. But it's quick and easy to make your own modern obi. Follow these steps:

1. Measure your waist and add 4 or 5 inches (more to make it overlap) to that number. Cut a rectangle of fabric that length by approximately 6 1/2 inches wide.

2. Cut medium-weight fusible interfacing 4 1/2 inches wide and the length of the fabric from step one, and center it in the middle of the inside of the fabric. Iron on the interfacing by following its included directions. Interfacing can be found at any sewing store, including Jo-Ann Fabrics & Crafts.

3. Fold over the edges of the fabric by 1 inch and sew at 1/4 inch from the edge of the fold.

4. Make a closure in the back with Velcro if your belt overlaps or — for the sewing savvy — use hooks and eyes.
