Rock Revival Jeans

Bought new at buckle.com in February. Style Amberlight Easy Boot, size 30/30 stretch jean. I still have the tags plus proof of purchase with buckle if need be. They became loose and baggy on me after a evening out. Since the tags have been removed after wearing them I cannot get a replacement size. I normally wear a 30" waist so this style runs a size larger for me. It's listed as a curvy fit though. You can look it up on buckle.com.
