What shop is considered the most fashionable in Bendleton in the novel, Midnight Bargain?

From the text:

“Tarden and Wallace was the most fashionable modiste in Bendleton, led by its Llanandari proprietress. Its design magazines were printed, bound, and sold to young women who sighed over illustrations of gowns that maximized the beauty of the wearer, with nipped in waists, low, curving necklines, and luxurious imported fabrics. This shop was the most expensive, and Father had paid for her wardrobe without a murmur” (17).
