Dillards is a bit pricey, but if your need is not immediate you can always wait for a sale. Go try them on now, and then watch for a sale. By the time a sale comes around, your sizes will be gone from the store (damn it), but you might be able to get them online, still.
And Dillards is still cheaper than Macy's. :'P
