Over on Stellar Four blog, on the 24th June, there's a post about awesome costumes created by and for people in wheelchairs. There's a tiny Eleventh Doctor in his Tardis, and a fairy-tale Cinderella, Oracle, Wall-e, and more. They're really inventive and truly wonderful.
It reminded me of the days when I used to go to lots of Star Trek conventions, back in the 1980s. One lady in a wheelchair took part in the fancy dress parade (cosplay was not even a word then!) as The Ship Who Sang. The spaceship costume was constructed around her wheelchair. I think this was probably at Leeds Dragonara Hotel (I went to quite a few conventions at the Dragonara, which has since changed its name). The lady could only go to conventions at all by making arrangements with the local hospital so she could stay with them for the weekend - she really was seriously disabled - but she was determined to enjoy herself when she got into the hotel.
