I'm interested in modifying shorts from the O'Neil brand for mass production while maintaining the same material and shape. Specifically, I'd like to switch the waistband to an elastic style with a drawstring and ensure both rear pockets have matching flaps. To proceed with these rebranding changes, please let me know what information or materials you require from me. I can provide pictures or even send you a sample pair of the shorts for better reference. Looking forward to your response!
