Hi there,
Having updated resolution (as eg no more XS) with nowadays resolution until 4K (could be great to adapt a design for XXL resolution (1920 or 2560 > 3840) ;
And why not based on Apple devices (somehow universal, as why not for Watch 
)
Brainstorm :
Name as clothes : S | M | L | XL | XXL
Other way considering non-“experts”, sizes and name as Apple devices :
- (Watch
) - iPhone
- iPad
- Display 24’’
- Display 4K
