Original athleisure hoodie brand design proposal

I want to design a complete proposal for an original athleisure hoodie clothing brand. Reference major sportswear brands, such as Uniqlo, MUJI, etc. It should be healing, comfortable, light luxury, and good-looking. Please output professional elements like brand positioning, brand name, visual system, product line, packaging posters, etc., and create a 4-image presentation brochure.
