One thing to try is those little travel sprays, so you could do that if you wanted to stay with the polyesters and rayons and avoid static. An alternative to those would be cotton. Look for a little bit of a thicker cotton. If there’s a little thicker feel to the fabric, then generally the fibers are a lot stronger. Be careful when you’re washing them. They should be fine in the washing machine, but when it comes to the dryer, cotton is known to shrink. Unless the garment is already shrunk, you want to think about line drying it. You’d need a warm iron at that point, so its hard to live without synthetics. There's also modal fabric that has the drape of rayon. It doesn’t have the static that you get with polyester, so that would be a good option to look at as well.
