Many young ladies assume that prom dresses that are made from synthetic materials are less valuable — and not really worth buying.  But prom dresses made with just a touch of synthetic material in the weave of the garment can make a much less susceptible to shrinkage — as synthetic fibers typically do not shrink as much as natural fibers such as cotton.  Because your garment will be less likely to shrink, you may find that you will get more use from your prom dress — it will turn out to be a much better value for the money spent, then a garment manufactured with 100% natural fiber.
