Lori Mid Rise Wide Leg Jeans

I read reviews and confirmed Rag and Bones online size chart many times before purchasing it, My normal size is 29, so I ordered a 28 ( of course all the reviews said it runs big) when I receive my pant, it's so big, it looks like pajama or a size 10 on me. Since it's a final sell item, I went to Nordstrom rack at Sandy store, Utah to check if I could exchange or get a store credit, the manager there today she is a total lier and rude, she basically said I can't even talk to anyone about this issue because it's a final sell, she doesn't have any interest to even see online measurements charts! What a disappointment.Well, Rag and Bones should be ashamed to make a style of pant that the measurements are not matching online denim measurements!!!! Now I stocked with a pant that doesn't fit!!!!
