I like the Gap or old navy. Levis is in a lot of stores JCpenney, kmart, Fred Meyer, Torid has bigger sizes.
I think when you said a clothes line people thought of higher priced places.
You can go to a lower price place like Kohls or Ross or TJ max so on and find name brands.
Even the 2nd hand stores have all sizes and better prices. Be creative and find your hot spot and pay less.
You can go into a high end town and go to the 2nd hand.
Find a place where you can return with no problems. Try your clothes on before leaving.
