I'm interested in designing some comfortable and affordable workout gear inspired by brands like Alo and Vuori. It's essential that the pieces we create not only feel great but also keep the cost low for our target audience. Could you share any existing samples or prototypes that align with this vision? I'd love to review what you have ready and discuss potential modifications to ensure they meet our desired quality and aesthetics. Thanks!
