Student looking for your advice and help to create a fashion line for people with disabilities

Im in my final year at Birmingham City University, Studying fashion design and communication, my work will be going forward to Graduate Fashion Week and all fashion designers high end and high street will be there too see it!
I'm looking to create a Sportswear Line for Men possibly unisex that gives the ease of wear and not difficult for people with disabilities to wear, as some may not be able to fasten buttons etc and this is where i need your help!

Have you got any advice for me? What do you think i could do to make clothing better and easier, what would you like to see! After all this is for them and to highlight the fact that there isn't anything quite like this on the market!
