Aloha, Skinny from Grand Junction, Colorado! We appreciate your feedback! We're also glad to hear you like the fabric better than what you've found in stores. We understand that the snug waist can be a concern, and we appreciate your flexibility with the ties. While we don't have a size 31 available, our commitment to high-quality products remains strong, and we're always working to improve our sizing. We've sent you an email to see how we can further assist and ensure your satisfaction. Thanks for being a valued Crazy Shirts customer.
