Dillard's is a good department store, offering apparel, accessories, shoes, cosmetics, and housewares. The range of their merchandise depends on the market that you're in. Over the past few years, they have moved to establish more of their own branded apparel & shoes, under names like Westbound, Antonio Melani, Kate Landry, and many others. I avoid these unless they're on a super sale.
The biggest downfall of this department store is that their pay structure (quota system) can create an uncomfortable shopping environment with pushy sales people fighting each other for sales.
