There are several options for clothing stores in the Huntington area. You have your typical stores at the Huntington Mall such as Macy's, Sears, JC Penny, Elder Beerman and several other typical/smaller stores. You can see the full list here.

Then downtown you have several other options. There are local favorites such as Wright's, The Village Collection and Wender's. Then at Pullman Square(also downtown) you have Chico's and another local place called Runway Couture, which has sister stores that sell just purses/accessories and one that sells just shoes.

There are also a few other local shops for more formal attire and there's also a place in Ceredo called the Rosetree that many people like. If you can't find what you are looking for in any of these stores, then Charleston is about 45 minutes away and has a few different stores you could check out but overall has about the same options. Hope this helps and let me know of you have any other questions.
