This is the only department store in the Chandler mall that has a decent big and tall section for men. I have always found the gentlemen working in that area to be helpful and not too pushy. Most of the stuff is Ralph Lauren and other name brands that I consider to be overpriced but they do have excellent sales and a ton of stuff gets marked way down on clearance at the end of the season so you just have to time it right. It is really your best shopping option in the area if you have a man in your life that is... well.... big and tall.
As another reviewer mentioned they also have an excellent selection of ladies dresses. And of course the best part about Dillard's is how the put those little stickers on your stuff so you can return it even if you loose the receipt.
