Polo State Men's Smoked Washed Baggy Fit Jeans

I whant change this one size different

Hello, I ordered two pairs of pants and both are labeled as size 33. The blue pair (size 33) fits perfectly, but the black pair, also labeled size 33, is extremely tight to the point that I cannot even wear it. I don’t understand how two items with the exact same size can be so different. This is very frustrating and clearly indicates a sizing or manufacturing problem. Please resolve this issue as soon as possible by arranging a replacement with the correct size or issuing a full refund. I look forward to your prompt response. Thank you.
