You don't have to try them on.
One size fits all.
I don't have to care whether the book:
- clashes with my complexion
- makes me look fat
- is dry clean only
- is season appropriate
- will go out of style next season
- fades, shrinks or bleeds colour
Glue and tape are the only things needed to repair any damages.
I can't complain about not having a pair of shoes to go along with a particular book.
And the best of them all - never, under no circumstances, ever needs to be bloody IRONED.
