retail design for autism spectrum disorder

I am in my last year of university studying design for branded space (spatial design/interior architecture). My objectives are to design an inclusive retail store for people with autism spectrum disorder without the sensory overload, I am working with Tommy Hilfiger adaptive clothing line. My design should aim for hyper and hypo sensitive autistic people. I am struggling to include materials in my space and would like to get some ideas. Tommy hilfigers clothing line aims to be functional, comfortable, yet still look like all his other clothing which made me choose his brand. I want to bring function and comfort etc in the space. I am attaching my site plan. I would like to get some design ideas I can have in the space focusing on the fabric aspect of the design and also how I could display the collection in a way that is autism friendly and respecting personal space. My vision for this right now is functional, comfortable and flow in space, I looked into biophilic design and want to introduce nature and organic forms but still adhere to Tommy Hilfiger adaptive. from the site plan I am using studio one and two. also need help thinking about sensory elements in the space. kind regards Naumana
