It would be easier to answer, to know what type of stretch pants one has in mind. Yoga pants, running pants and regular women's elastic waist pants could be considered stretch pants. Yoga and workout pants are available in all levels of quality and price points, at places like Big 5 sporting goods, REI, Sport Chalet, even KMart or Target. The elastic waist type of stretch pants would be available at a store like Walmart.

Most stores have a petite section. Kohls.com and Macy's have great selection of petite sized clothing. If you shop at J. Crew, they will hem the pants for you.
