Been searching for a denim "trucker" jacket since last fall and was happy to see that retailer had this in stock, purchased it online without thinking twice. typically, due to my small upper frame, i'm 5'4, 130lbs, 34 a for referance, i'm between a size small and an xs. bought both and opted for the size small when it arrived. 
i love the fit, slightly cropped in the back and i also like how it"s lined inside. great quality and perfect for fall!
