These Bibs run way small. I wear bibs daily working around my farm. I usually wear a 36X30 in any other brand of bib overalls. I ordered these a bit bigger(38X30) than I usually wear so I could wear a sweatshirt under them. They were very tight with just a t-shirt on. No, I have not put on any weight.  I contacted Amazon to return them and the only option was to return them for a refund, which will take 4 weeks to process. Amazon has not answered my e-mail asking to exchange them for a larger size. So it will be 6-8 weeks before I can get new bib overalls. Overall I have been completely disatisfied with this transaction. I hope this will not be the downfall of a company that has built itself on great customer service. Shoulda went to Wal-mart, I would be wearing my bibs by now :(
